    NOTABLE EVENTS OF THE PAST

      Red ball (924 bytes) 10 May 2011: Company Seven delivered another interesting optical system for NASA to fly later in 2011. This is a ruggedized and shock/vibration resistant catadioptric system with all optical components made fully quartz (fused silica), and with superbly engineered and applied high transmission coatings optimized for its designed transmission application. In order to maintain perfect focus at all operating temperatures the construction of the tube assembly and many mechanical components are largely of Invar, an ultra-low expansion aerospace grade alloy.

      Red ball (924 bytes) 5 November 2005 Company Seven supporting Howard Astronomical League "Mars Watch" event from 5:00 pm to 3:00 am. Company Seven provided a telescope and staff to see the Opposition of Mars at the Belmont Mansion, off Elibank Drive in Elkridge, Maryland. H.A.L. and Howard County Community College jointly sponsored this event which was open to the public at large. Company Seven assists at such events as a public service insisting on no promotional efforts on our behalf.

      The system furnished by Company Seven was our Astro-Physics 206mm f/8 EDF telescope with a Astro-Physics 90mm f/5 Stowaway "finder" telescope on an Astro-Physics 1200GTO German Equatorial Mount. The system was equipped with our Baader Mark V Großfeld Binocular Head, a top of the line system providing high resolution binocular views through the telescope. We employed a selection of TeleVue Panoptic, TeleVue Nagler, TeleVue Radian, and a matched pair of Carl Zeiss Abbe Orthoscopic series eyepiece sets and filters. While this was a good "practice run" for us, the seeing conditions were marginal with notable humidity and sky glow. Therefore, the telescopes were limited by seeing conditions to moderate magnifications on the order of 300X or less. Regardless of the seeing limitiations, the large number of visitors were nonetheless enthralled by Mars. Later in the session we did study a number of the brighter popular deep sky objects, and later Saturn!

    Recent Changes at C7's Web Site

      Owing the the increasing size and complexity of our site, we will work to update this page in order to help our customers find the changes or news of interest.



    Changes in July 2017:


    • Questar Tristand or Astropier Riser (17,105 bytes) Company Seven announced the Questar Tristand Riser. This is our new precision machined accessory that increases the payload elevation clearance capacity for the fork mounted Questar 3-½ telescope when the set is employed on either the Tristand or Astropier.

      Right: Company Seven’s Riser, an optional solution improving elevation clearance for the Questar Tristand or Astropier, shown installed (17,105 bytes).
      Click on image to see enlarged view (72,480 bytes).

      The Sun will rise to it’s highest elevation in the sky near noon each day, in our Washington D.C. area for example on the day of the Summer Solstice the Sun will rise up to 74 degrees above the horizon. In June of 2017 Mr. D. Illig, one of our local clients, was preparing to image the coming August 21 Total Solar Eclipse of the Sun. He noticed that when his large Canon EOS digital SLR camera was attached to his Questar 3-½ telescope, the curved northern tip of the Tristand Head Elevation Axis hindered his pointing the Questar 3-½ telescope high enough to reach the Sun.

      We have been offering the elegant Tristand, and a taller version marketed as the Astropier too, for some decades with only one other client ever before contacting us about experiencing this limitation. For that client Company Seven developed a cylindrical extension that could be attached onto the Tristand Head platform, this elevated his telescope and provided enough clearance so that he could photograph the Sun at any time of the year from his location. Given the increasing bulk of DSLR cameras, and also motivated to help Mr. Illig, Company Seven revised our prior solution and in July 2017 introduced our revised Riser.

      Company Seven’s Tristand Head Riser allows a Questar 3-½ telescope with a larger camera or other payload attached to point up to higher elevations of the sky. The construction of Company Seven’s Tristand Head Riser fully matches the material and finish of the Tristand furthermore, this does not compromise rigidity or stability of an attached telescope.



    Changes in April 2017:


    • Bausch & Lomb Telescopes: for day and night use, catalog of 1929 Bausch & Lomb Telescopes: for day and night use, catalog of 1929, the complete twenty-eight (36) page illustrated booklet describing the Bausch & Lomb telescopes and including prices of many of the items mentioned. At the turn of the last century and going into World War II Bausch & Lomb, established in Rochester, New York, was a manufacturing powerhouse: a preeminent maker of raw optical glass, of binoculars, camera lenses, and other optics too. They, along with nearby Kodak and other manufacturers with whom they had relations, including Carl Zeiss Jena of Germany, set the tone for innovation and development of new technologies in optics and photography among other fields. Many of their consumer products were designed and manufactured by Bausch & Lomb however, their company had licensing agreements with other makers and so it would not be uncommon to find a Bausch & Lomb was other than in labeling identical to one made by Carl Zeiss Jena for example.

      This catalog was published in the post “Great War” era, at the time Bausch & Lomb company marketed telescopes for terrestrial or panoramic observing, for astronomy, and other pursuits. So this booklet provides an insightful overview of the times as they relate to Bausch & Lomb#46;s marketing of telescopes to consumers, to universities, and to other too. This commencing with an aerial photograph of the B&L plant, taken with their Ic Tessar lens (designed by Carl Zeiss Jena, manufactured by B&L under license). This also features photographs of their telescopes including a B&L 11 inch diameter f/15 refractor on their German Equatorial Mount in their new factory observatory and elevating floor, of scenery and architecture of that time.

      The catalog goes on to explain how the B&L telescopes are available for terrestrial applications while larger or more sophisticated models were made for uses involving astronomy. Pages detail and illustrate their 60mm, 80mm and 102mm telescopes, include specifications, and itemize included accessories. The prices of several popular models of telescopes and accessories are included however, given these costs these certainly were sold only to those persons of some means, or organizations since the price even for a small 60mm telescope was the equivalent of several months of an average American’s home mortgage payments. Their equatorially mounted telescopes appear to have been marketed here primarily to educational organizations, with larger models for universities seeking to advance their educational programs and make a statement by funding their own large astronomical observatory. One could order a complete telescope optical tube assembly with or without mount, or order a telescope objective lens set alone; this catalog lists 25mm up to 152mm (6 inch) objectives ranging in price from $12.00 up to $400.00 though the larger 127 and 152mm objectives being made to order. Among the aspects that we at Company Seven found most interesting were the explanations of the provided accessories and optional accessories too including: various designs and focal lengths of available eyepieces, their zenith prisms and the triple revolver for astronomy and the image erecting prisms for terrestrial work, sun glass and ray filters, and the Herschel Eyepiece (Herschel Wedge) for studies of the Sun. Eyepieces explained include Huygenian models in focal lengths of from 8.5mm up to 60.89, and Orthoscopic models of from 6mm to 32mm focal length. Tripods, stands, driven setting circles for German Equatorial Mounts, and other items are mentioned.

    Changes in March 2017:


    • Bausch & Lomb Stereo-Prism Binoculars Catalog of 1923 Bausch & Lomb Stereo-Prism Binoculars, catalog of 1923 This month we scanned another original document in our C7 Collection Items Articles & Archives. This is the complete twenty-eight (28) page illustrated booklet describing the Bausch & Lomb prism binoculars. You might know them today for making sunglasses and contact lenses, but decades ago Bausch & Lomb, established in Rochester, New York, was a manufacturing powerhouse: a preeminent maker of raw optical glass, of binoculars, camera lenses, and other optics too. They, along with nearby Kodak and other manufacturers, set the tone for innovation and development of new technologies in optics and photography among other fields. This catalog was published in the post “Great War” era, at the time Bausch & Lomb Company marketed binoculars to consumers for sporting, birding, boating, and other pursuits.

      This booklet provides an insightful overview of the times as they relate to the marketing to consumers by Bausch & Lomb of their binoculars. This is a bit of a time capsule from the era commencing with an aerial photograph of the B&L plant, taken with their lens. This featuring photographs taken at an automobile race, of scenery and architecture of that time - most likely gone now.

      The catalog goes on to explain how the B&L binoculars are constructed showing their layout, and with illustrated explanations how they differ from then still popular Galilean binoculars and why their Porro show a superior stereoscopic perception. This includes discussions about how to select a binocular: magnifications and why the choice matters, judging clearness of field, alignment, and to select a binocular for the various typical uses. Page 13 indicates the specifications and pricing follow, though the places for prices are left blank, then each model of B&L Porro binocular is described and illustrated. This includes their central focus models: 6x 25 mm, 6x 30 mm, 8x 25 mm, 8x 30 mm, and the individual focus ’10x 45 Marine Glass’.

This is available on request only for those of our customers who have made it possible for Company Seven to survive and prosper over the decades.



    Changes in January 2017:


    Changes in November 2016:

    • Updated our Company Seven's Astro-Physics Telescope and Mount Availability page to reflect that we are now accepting orders for the 2017 production Astro-Physics 13cm GTX Gran Turismo telescopes, featuring a 3.5 inch diameter focuser these are the successor to the prior Astro-Physics 13cm EDF Gran Turismo telescope. Invitations to those customers of Company Seven who registered on our waiting lists commenced going out.

    • Lunt SUNocular solar binoculars assortment at Company Seven (79,574 bytes) The SUNocular and SUNocular-Mini binoculars were introduced by Lunt Solar Systems to provide the user with a compact, convenient, and affordable means of safely observing aspects the Sun including Sun Spot activity (magnetic storms) or Planetary Transits. These were developed specifically with the impending Total Solar Eclipse of August 2017 in mind where millions of people across much of the USA will be able to observe this rare even.

      Right: Lunt SUNocular solar binoculars shown at Company Seven, note the opaque solar filter elements over the objective lenses (79,574 bytes).
      Click on image to see enlarged view (322,960 bytes).

      The innovative SUNocular does at first glance appear to be a conventional central focus roof-prism binocular however, the SUNoculars incorporate glass solar filter elements that so reduce the amount of light passing through that these are suitable solely for examining intensely bright objects such as the Sun. These filters are an integral component that cannot be removed (or lost) this the SUNocular cannot be employed for the observation of terrestrial objects. The light from the Sun is reduced to a comfortable level for observing, while harmful ultra-violet and infrared components of that light are completely and safely blocked. The full size SUNocular is so compact and useful that Company Seven is stocking this, ordering the small 6x SUNocular-Mini only by request. This article profiles the SUNocular 8x model.



    Changes in May 2016:


    • cover of Bausch & Lomb Life Long Binoculars, catalog and 1934 price sheet (21,027 bytes) This month Company Seven pulled more information from our archives for scanning. This latest document is even more interesting to read that we might have imagined, it is the Bausch & Lomb Life Long Binoculars, catalog and 1934 price sheet, the complete forty-five (45) page illustrated booklet describing the Bausch & Lomb binoculars and field telescopes.

      You might know them for sunglasses and Contact lenses, but decades ago Bausch & Lomb, established in Rochester, New York, was a powerhouse: a preeminent manufacturer of optical glass, maker of binoculars, camera lenses, and other optics too. They, along with nearby Kodak and other manufacturers, set the tone for innovation and development of new technologies in optics and photography among other fields. Up to the time this catalog was published the Bausch & Lomb Company marketed to consumers however, it was also instrumental in supplying the United States military with optical instruments that would continue well throughout the coming World War II and beyond. Though by the 1950’s they had commenced exporting many of their U.S. based jobs to Japan thereby becoming among the first U.S. companies to sell their soul; they would never again regain their dominance or mystique in those fields.

      This booklet provides an insightful overview of the times as they relate to the marketing by Bausch & Lomb of their binoculars. This explains their properties including: differences of designs (Galilean versus B&L prism models), explanations of the Central and of Individual Focusing mechanisms, about magnifications and how they matter, judging clearness of field, alignment, and their stereoscopic effect. This also explains how these are constructed showing their layout, and with illustrated explanations how to select a binocular for the various typical uses.

      Then each basic model of B&L binocular is described and well illustrated including: 6x 30 mm, 7x 35 mm, 7x 50 mm, 8x 30 mm, 9x 35 mm, 10x 50 mm, and 10x 45 mm. The document also includes testimonials by naturalists, hunters, and Olympic sports team members. The numerous good quality photos showing people of this era, their clothing, etc. adds some additional interesting history context even beyond the optical subjects of the booklet. Content scanned from original in our archives in moderate resolution and provided by Company Seven as an Adobe pdf file (7,067,715 bytes); this is for clients of ours by request only.

    • "Carl Zeiss - A History Of A Most Respected Name In Optics" This month we did some work to increase content and better format this illustrated article that is one of the older articles at Company7.com. We are also including images and scans of Zeiss items exhibited at our showroom, as well as some literature scanned to complement the article from our Zeiss archives.

      With some of the content in our article dating back to 1994, when slow dial-up Internet access was the norm for most readers, the article was text heavy because illustrations were by necessity kept to a minimum. Over the decades we have and will on occasion add this or that illustration of items in our museum collection to break up the monotony of text, or make corrections (with much gratitude to contributors), clarify and expand information about content as we pull more information from our own archives. It was never our intent to write a comprehensive and all encompassing history of Zeiss, that would require volumes to do it justice, but rather to show why we at Company Seven were and remain in awe of the company achievements.


    Changes in April 2016:


      eyepieces and prisms covers of our Mark 37 (21,027 bytes)
    • On 23 March 2016 Company Seven acquired a U.S. Navy issued 9x 63 Porro Prism binocular, specifically a Mark 37 made in 1944. This was our second World War II era U.S. military issue binocular, and is now on permanent exhibit at our showroom museum among our collection of interesting or significant optics. This Mark 37 is displayed near our recently acquired Bausch & Lomb Mark 28 Mod 0 and U.S. Navy Mark XLIV 7x 50 SARD binocular, also from 1944. In time we will acquire, exhibit, and write about others.

      We were pretty excited about finding a Mark 37 binocular in good condition because:

      1. it was made, and not in great numbers, specifically for use by the Captains of the Battleships and Cruisers of the greatest naval force ever engaged in war: the United States Navy*,

      2. this typifies that famous Yankee Ingenuity, in this case where production military binoculars were adapted to serve a different purpose,

      3. and the organization that produced these was the Washington Navy Yard optics shop – in itself an interesting story.

      4. This was developed by The Greatest Generation: men and women who developed a qualitative edge in technology, superior manufacturing capacity, and who made up the forces that with adaptable leadership and some guts too defeated Hitler, Hirohito, and their minions.

      5. And finally, the tie in to the fictional British Secret Service agent James Bond 007 was too irresistible to overlook.

      The excitement needed to be shared with those who have helped to keep Company Seven around for well more than three decades, and so we elected to write about the U.S. Navy Mark 37 binoculars too. This article will contain some informational overlap with that content in our previously published article about the U.S. Navy Mark XLIV 7x 50 SARD binocular. We have worked to minimize overlap except where it helps either article stand on it’s own.

    Changes in January 2016:

    • Updated Company Seven's Questar section to include the FR-1 MKIII Long Distance Microscope. The Questar FR-1 is a high resolution long distance microscope that differs from other Questar LDM’s in that it’s range of focus spans not only from near but also out to infinity. The FR-1 provides a working distance to the object of study from as close as 91cm (36 inches) and to as far away as infinity and so this instrument is suitable for imaging from it’s near focus limit out to the Moon and beyond. This allows the FR-1 to be employed at greater distances from the subject of study all the way out to infinity as an ultra telephoto lens with a diffraction limited field at prime focus 18mm diameter at the focal plane or even larger with the use of auxiliary lens elements. The optical resolution capabilities can reveal detail as fine as 6 microns at the closest working distance.

    • On 8 January 2016 we celebrate thirty-six (36) years as a licensed business while defining competence and integrity in our community, with more than thirty-two (32) of these years at our Laurel, MD showrooms. The original telescope showroom opened 1 October 1984, we outgrew that and relocated in 1 October 1986 to our present location on Cherry Lane Court.

      To make note of this we have updated the artwork at our home page to reflect this.

    • One further note, the articles about telescope products and our other content at Company7.com were intended to inform and amuse customers and fellows of like mind in our community. Unfortunately, we have encountered rampant plagiarism and copyright violations of our content; some less-knowledgeable retailers have been stealing much of the knowledge, test data, and photos we have created, then have hosted that content at their own web sites. Because of this we have pretty much slowed or discontinued altogether providing advice on line, or updating the consumer products sections at our web site that could benefit the E-Tailers. Instead we prefer to speak with customers one at a time, or have them visit our showroom.

      Unitron 4 inch (102mm) Model 152 and 3 inch (75mm) Equatorial Refracting Telescopes at Company Seven (23,985 bytes)
    • Last month we announced the acquisition of a 1980’s era Unitron 4 inch (102mm) f/15 Model 152 Equatorial Refracting Telescope for our exhibit, we show a photo of this impressive telescope at right. The telescope, complete with the original wood packing crates for the optical tube assembly and German Mount Head, arrived on 18 August from a collector in Belgium. After nearly four weeks of work we completed our illustrated article explaining these telescopes, and now this 4 inch telescope joins our other Unitron telescopes at our on-line virtual museum. The article Unitron Model 132 - 4.0" (102mm) Achromatic Telescope is now listed among other articles pertaining to these products at UNITRON Library Section.

      Right: Unitron 102mm (4 inch) and 75mm (3 inch) equatorial refracting telescopes as displayed at Company Seven; note our ceiling height is 9-½ feet. (23,985 bytes).
      Click on image to see enlarged view (64,198 bytes)

      In time we hope to add some optional accessories for the 4 inch telescope including the Unitron mechanical clock drive, a weight-driven motor based on the mechanics of a clock but geared to rotate the telescope Right Ascension axis about once every 24 hours. We already have some offers of help to add some other hard-to-find accessories for this telescope, these will be acquired over time for our exhibits. While many other people no doubt have accumulated extensive collections of telescopes, including Unitron and Polarex, we know of no where else where the public is welcome to visit and can be so impressed by the presence of those telescopes that helped to stimulate interest at the beginning of the space age as at Company Seven.

      Each article we host about Unitron telescopes already in our display explains the history of these telescopes and of Nihon Seiko Kenkyusho, Ltd., the company based in Tokyo that made them in Japan until 1992. We expanded our introductory index page of our Unitron section to explain how these telescopes were marketed around much of the world under the various trademarks: POLAREX, SEIKO SCOPE, UNITRON, MERIDIAN, and WELTBLICK (World View).

    • Look for a new presence of new Lunt Engineering products coming soon for display and sale at Company Seven. More about these products in time.


    Changes in August 2014:

    • Announced in our UNITRON Library Section the acquisition of a 1980’s era Unitron 4 inch (102mm) f/15 Model 152 Equatorial Refracting Telescope to our collection, and we show a photo of this impressive telescope here too. The telescope, complete with the original wood packing crates for the optical tube assembly and German Mount Head, arrived on 18 August from a collector in Belgium. This late production antique instrument is in uncommonly good condition, with some components still wrapped and unused as they were sent from the Nihon Seiko factory in Japan. The set underwent conservation and preparation to join our exhibit on 27 August alongside its smaller cousins, our Unitron Model 142 - 3.0 inch (75mm) and Model 114 - 2.4" (60mm) telescopes already on exhibit at our Laurel, MD showrooms. Concurrently, we are preparing an illustrated article so that this 4 inch telescope will join our other Unitron telescopes at our on-line virtual museum as well.

    • Acquired a new DayStar Hydrogen-Alpha Filter for use at our Solar Saturdays observing sessions. This is a DayStar QUANTUM SE 0.7Å filter, one of a series that maintain their nominal bandwidth regardless of ambient temperature, and that should provide stunning views (and images) of photospheric activities on the Sun. We intend to add a snapshot of this filter to our on-line explanation of these filters.


    Changes in July 2014:

    • Updated our NRD Staticmaster® section to include additional information from our archives that explains some of the history of the Staticmaster brushes and the founding company, Nuclear Products Company that developed the product some sixty five years ago. Into our articles we incorporated images of several older Staticmaster brushes with their packing cartons from our collection. Furthermore, we scanned some of the original literature that accompanied the Staticmaster, and we are gradually posting these documents at Staticmaster Notes & Interesting Articles section.

    • Reviewed and expanded our page explaining Baader Planetarium AstroSolarTM solar filter media page to help our customers better understand the strengths of these white light filters. We took images of the Sun on 5 July 2014 at about 12:45 pm E.T. just outside Company Seven's showroom. Note, these are simple snapshots taken with a Canon Powershot S100 pocket digital camera simply handheld over the eyepiece! The images compare the details of sunspots as seen through a Lunt Solar Systems hydrogen-alpha filter and through the AstroSolarTM film. Still, these images cannot quite convey the dynamic ranges of color and tones, nor the clarity and sharpness of details of the sunspots as they were observed by the eye.

    • Added information to our Library section article "Ultraviolet Spectrum Primer", and we better arranged the page to allow easier understanding of the available literature and access to some of the related documents that we have scanned and host in support of this subject. This illustrated article by Company Seven explains the ultraviolet (UV) spectrum as it applies to photography or imaging objects in the UV. This includes and explanation about the UV spectrum (UV-A, UV-B and UV-C) that we can readily work with. We also discuss specialized imaging gear including the Nikon UV-105 lens, the discontinued Zeiss Hasselblad UV-Sonnar lens too, and some of the cameras made for this specialized work.

    Changes in April 2014:

    • Commenced sending invitations for registered customers to order from the Summer 2014 production run of the Astro-Physics Mach1GTO German Equatorial Mounts that are well underway too, we expect to commence making deliveries of these mounts in July 2014. For these products we refer to our waiting lists, sending invitations to notify people who have registered. Accordingly we have updated our Astro-Physics Telescope and Mount Availability information page.

    • Updated our DayStar Filter section to reflect announcement of a new arrangement of specialized filter. In our news article DayStar Announces QUARK Hydrogen-Alpha Filters, we describe what is an unprecedentedly successful marriage of Hydrogen-Alpha filter and beam-shaping optics that succeeds in being: Quick, Cheap, Easy and Fun to use. It is compatible with most telescopes or lenses of f/4 to f/9. Just slip the lightweight QUARK assembly into the diagonal or focuser of your telescope, slide an eyepiece (or camera adapter) into the 1.25 inch diameter accessory holder, connect USB power, and you are off and running - and on band year round!

      This new filter is described in our web page section about production DayStar Hydrogen Alpha Filters. One of the first production QUARK 0.7Å filters will be on hand at Company Seven by April 19 for use at our 'Solar Saturday' sun observing sessions, so you may visit Company Seven to see one in use for yourself. Company Seven has been accepting orders for the QUARK since 1 February, while this new product was announced to the public later on 1 April 2014. Contact Company Seven, preferably by E-Mail to order yours or to learn more about this interesting and fun accessory.

    • Hosting news article that is gradually circulating around US Government circles and leaking to the news media about the recent (formerly) secret visit of a head of state to Company Seven. We will have no further comments about this but instead encourage inquiries to the respective police and government agencies that are investigating.


    Changes or news in February 2014:

    • Updated our Company Seven's Astro-Physics Telescope and Mount Availability page to reflect that we are now accepting orders for the 2014 production Astro-Physics 13cm EDF Gran Turismo telescopes. Invitations to those customers of C7 who registered on our waiting lists commenced going out.

    • Sean League, Sales Director of DayStar Filter Company visited Company Seven on 1 February 2014. Sean is one of the few sales representatives that have been welcomed over the recent decades at Company Seven since he brings perspective from the viewpoint of an enthusiast first, with the experience and understanding gained from operating his own telescope store that he previously operated in Oregon. Sean brought a sample of DayStar's new 127 telescope that incorporates a Hydrogen-Alpha filter, and surprisingly enough the weather Gods smiled upon us and allowed this "Solar Saturdays" observing session at Company Seven to actually see the Sun and not suffer the record cold that our region had been enduring throughout January.

    • We have commenced updating our DayStar Filters section information pages, and we added photos and mention of Sean's visit at our DayStar News page. We have been hesitant to update product lines pages at Company Seven over recent years since the industry has become dominated by E-Tailers, most whom do not know the equipment as well as we do and whom have been referring to our web pages for product knowledge and at times even stealing our copyrighted content. DayStar management is among the few in our industry who appreciate the value of having brick front stores that know the product, that can show and support it for their customers. And so we will resume updating our DayStar section for the benefit of our astute clientele.


    Changes in January 2014:

    • On 8 January 2014 we celebrate thirty-four (34) years as a licensed business while defining competence and integrity in our community, with more than thirty (30) of these years at our Laurel, MD showrooms. The original telescope showroom opened 1 October 1984, we outgrew that and relocated in 1 October 1986 to our present location on Cherry Lane Court.

      To make note of this we have updated the artwork (shown at right) at our home page to reflect this.

    • Astroscan of 1976 (43,757 bytes) Company Seven acquired another very early production version of the Edmund Model 2001 for our museum collection of telescopes; this is among those amateur telescopes that were significant to the development or promoting of our hobby since the start of the Space Age. This was among those sold by Edmund Scientific Company, then based in Barrington, N.J., well before a contest that concluded in November 1976 determined what was formerly marketed as their "Wide Field Telescope" (Model 2001) would henceforth be known as the Astroscan.

      Left: the serial number 152 on the Model 2001 telescope now on display at Company Seven (67,889 bytes).

      For Company Seven this could be no average Model 2001, we had to find something more interesting than the other hundred thousands made to date: we now show telescope Serial No. 152. This was made very early in the first production lot; this was back when such things were actually made in the USA while now all new Astroscans are made in (take a guess) China. This telescope replaces 2075, our previous old-timer on display. This 102mm clear aperture 445mm focal length f/4.2 Newtonian telescope (the lens at front is a flat glass window) was completely disassembled, cleaned and conserved. Other than making an exact duplicate charcoal polyurethane foam disc that backs the Primary Mirror to replace the original spalling foam, we did not replace any original components but cleaned and restored the entire assembly. Nor did we see any need to strip and recoat the optics after a professional cleaning, but left them original. SN 152, now fully assembled and collimated at Company Seven, is now on display at our showroom. Our team devoted a ridiculous amount of technician and optical bench time doing this - but nobody ever before accused Company Seven of operating like a business. In time we may host an illustrated article about these telescopes at company7.com.

      The Astroscan is quite a compact simple to use arrangement, and yet is a comparatively ruggedly built portable telescope. These were introduced in September 1976 with a goal of selling eight hundred, but by Christmas more than two thousand of the first three thousand sold had been delivered. These helped many newcomers enjoy their first exposure the hobby, and were a good choice for some who simply sought a more compact second wide field telescope. Astroscans are at their best introducing those who want to learn their way around the night sky, observe the Moon and other brighter objects. These remained especially popular while Company Seven sold them throughout the Comet Halley era of 1984-1985 though we discontinued selling them soon after when production shifted to other facilities. Furthermore, with the introduction of reasonably well made imported Newtonian telescopes with Dobson-style mounts (such as our Orion compact six-inch StarBlast 6), the Astroscan has not provided as great a value for most of our customers as it once had.

    Changes in May 2013:

    Changes in April 2013:

    • Remembering Bruce Roy Wrinkle (b. 7 August 1945, d. 28 April 2013). Bruce was the soul of our showroom; kind, witty, intelligent, and able to greet you with a funny (or corny) joke and great advice. Bruce was was amazingly well read, able to hold conversations with doctors and scientists on matters as diverse as prions or the physics of dark matter. He was our friend, a true friend in every sense of the word and every day without him lacks some luster. Here we also posted information about funeral arrangements for those who wish to help send him off.

    • We have updated our Astro-Physics Telescope and Mount Availability information page and commenced sending out invitations to those lucky people who wish to buy the 130mm f6.3 EDF Gran Turismo Triplet Apochromat telescope.

      Company Seven has one last new 1200GTO German Equatorial Mount and one new Model 900GTO mounts (from the last production lots) on static display at our showroom. We will rotate out the 1200GTO and 900GTO mounts to replace them with the 1600GTO and the new 1100GTO mounts. It is possible that we may be receiving some 900GTO and 1200GTO mounts in trade or on consignment as some customers will want to upgrade their observatory, so this may help customers seeking a more 'transportable' alternative to the 1600GTO and a lower cost alternative to the 1100GTO with the 900GTO.

    • Hosting news article that is gradually circulating around US Government circles and leaking to the news media about the recent (formerly) secret visit of a head of state to Company Seven. We will have no further comments about this but instead encourage inquiries to the respective police and government agencies that are investigating.


    Changes in March 2013:

    • Introduced a new product to the American markets, that will be for North and South America: the instructional DVD How To Become and Expert Solar Imager DVDHow To Become and Expert Solar Imager. This instructional DVD resulted from a collaborative effort by Ninian Boyle and Pete Lawrence, two experienced amateurs who are using solar filtered telescopes the same as those you can buy from Company Seven. Their DVD presents information in a comprehensible manner explaining what types of imaging you can do whether it be white light imaging of the Sun or using the more interesting modern hydrogen-alpha filters and telescopes; they conduct you through the entire process step by step. Their work has featured prominently in works by the BBC (British Broadcasting Corporation), astronomy publications, as well as in advertisements for companies that manufacture equipment for amateurs and professionals including Coronado and Solarscope Ltd. for example.

      The DVD is authored to be read only by a personal computer, not by a conventional DVD video player, and as such has no Region restrictions as do conventionally authored DVDs. This content includes:

        • More than two and one-half (2-½) hours of instructional video covering topics including what to use, how to capture images, and the final post-processing of the image data to produce stunning pictures.
        • FREE image processing software*: all that you'll need to commence processing and finalizing your images.
        • Sample processed images and videos supplied by Pete for you to refer to, and
        • unprocessed images and videos supplied by Pete so that you may practice processing; you can make your mistakes in safety!

      This item is so well proved and received by those in Europe who can order it directly that Company Seven has elected to distribute this for the Americas. Customers in Europe can continue to order direct from the authors in the United Kingdom. Furthermore, this is the first item that we will allow to be ordered on-line directly from Company7.com. Deliveries will commence at the end of this month and you will be able to buy a copy at our showroom in Maryland too.

    • Commenced hosting our section describing the Solarscope Ltd. Hydrogen-Alpha (Hå) solar filters and filtered telescopes from the Isle of Man, in the United Kingdom. This choice makes Company Seven only the second retailer and most likely to be the only showroom environment where one can visit to see Solarscope Ltd., DayStar, Lunt, Solar Spectrum, and other top line solar observing and imaging products routinely on display in the Americas and also meet with competent experienced sales representatives. Of course we will invite feedback and images from our Solarscope customers too! Company Seven commenced deliveries this month and we anticipate the arrival of the first of systems for display and use at our activities about in time for the Easter 2013 holiday season - how appropriate with which to enjoy sunny Spring days!

    • Eyes To See: Observing the Nearest Stars Added another title to our list of our most recommended books; the book Eyes To See: Observing the Nearest Stars is written by a customer of Company Seven, who got his start into visual astronomy not too many years ago. So this is an excellent read not only for those seeking a guide to how to find some interesting stars in the night sky and their history, but about how astronomy just might help you to find yourself.

      Looking up into the Heavens on a clear night under a dark sky, we can easily fool ourselves into thinking that the brightest stars we see are those closest to us. The reality could not be more different! In fact, 19 of the 25 closest stars to the Sun are invisible to our naked eye, and many are actually so faint that even with the modest equipment owned by most amateur astronomers, they can be supremely difficult to find. "Eyes To See: Observing the Nearest Stars" takes the reader on a one-year guided tour through the regions of the Milky Way galaxy closest to our own solar system, concentrating on practical hints at observing this region for one's self.

      This is another of those wonderful books that are difficult to find in a store. Company Seven found it to be such a practical and enjoyable read and reference work, that is also thought-provoking on several other levels too so that we wish to share this with our friends. We will make a special effort to stock this title, and to make it available as a .pdf title for those who seek such portability and convenience.


    Changes in February 2013:

    • Put on line a new section describing the Lunt Solar Systems Hydrogen-Alpha (Hå) solar filters and filtered telescopes. Company Seven picked up the Lunt product line in 2012 at the suggestion of some of our customers who were impressed with their handiness, and remarkable images; they provide a great return especially given their cost is not all that beyond reach of die hard amateurs or schools. The Lunt Hydrogen-Alpha (Hå) file red telescopes have since become regular show-stoppers at the Solar Saturday observing sessions by our showroom in Maryland.


    Changes in January 2013:


    Changes in November 2012:

    • Added additional information and images detailing the Ultra Violet Products Ultraviolet Cabinets. These are compact enclosures designed specifically to provide a portable cabinet for the inspection of samples illuminated under ultraviolet emissions. We emphasized the UVP C-65 Chromato-Vue® observing cabinet, a model so versatile and of high performance that the owner of Company Seven bought one.

    • Added additional information and images explaining the history of Unitron telescopes, this included expanding our write ups of the Unitron Model 142 - 3" and "Unitron Model 114 - 2.4" achromatic refracting telescopes that Company Seven acquired for our museum collection and display.

    • Expanded our introductory article explaining the history of Questar Corporation and their telescopes at Questar Index page. This included images of their first advertisement scanned from our archives.

    • Added additional information and images detailing the Zeiss Sports Optics Warranty, Repair & Service that apply to most binoculars, riflescopes, and electro optics (Range Finders, Night Vision Optics). Also commenced gradual updating and expansion of our article Carl Zeiss - A History Of A Most Respected Name In Optics; this article is among the older ones at Company7.com and as such is comparatively text-heavy so will will refine the article layout and add photos, mostly of Zeiss artifacts in our collection, to make the article more pleasing to the casual reader. Refined infrastructure to accommodate future expansion of our Carl Zeiss section at will.


    Changes in October 2012:

    • Solarscope Ltd. from the Isle of Man, in the United Kingdom have agreed to distribute their amazing Hydrogen-Alpha Solar Filters and Solar Telescopes through Company Seven. This choice makes Company Seven only the second retailer and most likely to be the only showroom environment where one can visit to see Solarscope Ltd., DayStar, Lunt, Solar Spectrum, and other top line solar observing and imaging products routinely on display in the United States (if not all the Americas) and also meet with competent experienced sales representatives. Furthermore, in keeping with our Solar Saturday's social gatherings, our customers and visitors will have opportunities to see the top of the line Solarscope DSF-70 and Solarscope DSF-100 double stack systems (selectable 0.7Å or 0.5Å bandpass) at work outside our showroom. As we become better acquainted with the Solarscope products we intend to dedicate some effort to host illustrated articles explaining these rarely seen systems at Company7.com. Of course we will invite feedback and images from our Solarscope customers too! Company Seven already has some systems in the production queue, and so we anticipate the arrival of the first of these systems about in time for the Easter 2013 holiday season - how appropriate with which to enjoy sunny Spring days!

      We have dramatically beefed up our book selection with many of the most recent titles that pertain to: observing and imaging the Sun, latest knowledge about features on and within the Sun (including the sunspots, prominences, and the solar tachocline), as well as some reprints of much older books that demonstrate the history of solar studies and the perceptions of those who preceded us in solar studies.

    • We updated our TeleVue News and TeleVue Pricing pages to reflect the factory authorized sale in effect between 1 October and 28 December 2012. This will be a great opportunity for customers, especially those seeking to build a new eyepiece selection or upgrade their existing set, to acquire the latest offerings from TeleVue.

      The sale applies to all current production eyepieces* (including new Delos), Barlows, Powermates and Paracorr. Commencing Monday 1 October through Wednesday 28 December 2012, save ten percent off our normal pricing on all current production TeleVue eyepieces and most auxiliary optics. Yes, this is a factory authorized sale that includes all the latest production TeleVue Ethos and Ethos SX, and Delos eyepieces. This will include the newest Delos 3.5, 4.5, 8.0, 12, and 14 mm eyepieces that will be introduced later this month. The sale also includes all the TeleVue Nagler series (Type 4, Type 5, Type 6) eyepieces including the Nagler Zoom, Panoptic, and Plossl eyepieces. Also included in the sale are the TeleVue coma-correcting visual and imaging Paracorr 2 lens, and their Barlow and Powermate lenses.

      *The Radian eyepieces are not included in this sale as they are being gradually phased out, and stock remains only of some focal lengths.

    • Near the close of our business day some week or so ago Company Seven answered an urgent telephone call from a hospital Emergency Room in Texas, a doctor was inquiring about poison control procedures for our Carl Zeiss Lens Cleaning Fluid; this is one of only two products of its kind that we endorse. Apparently some small child ingested the contents of a small bottle of the lens cleaning fluid, and there was nowhere else for the doctor to obtain information quickly about how to deal with this. In response to that incident we have taken it upon ourselves to assure the Materials Safety Data Sheet for not only the bottled solution but also for the lens cleaning toilettes are hosted in our Zeiss Library section.

      In addition to describing these articles in our Library index, we also mention them here with the hope that the information may more quickly be picked up by the Search Engines for dissemination:

    • Made some other minor updates to various pages within our site, including a bit of Internet social commentary at our How To Contact Company Seven page.

    • Look forward to an interesting announcement about a change at Company Seven coming soon - a first in our nearly 33 years of operation!


    Changes in August 2012:

    • Commenced sending invitations for registered customers to order from the first production run of the new Astro-Physics 1600GTO German Equatorial Mounts that are well underway too. We expect to commence making deliveries of these mounts in October of 2012 through March or April 2013.

      The 1600GTO replaces the 1200GTO in the product lineup, featuring 1. an increased payload handling capacity of up to about 200 lbs. to manage RC telescope with working payloads up to about 20 inch aperture for example, with 2. the option to have new or added later one or both 'absolute' encoders - particularly beneficial for remote observatory control, and 3. the Periodic Error spec of 5 arc seconds (+/- 2.5 arc sec.) is the maximum native mechanical error inherent in the mount's RA axis WITHOUT any software correction. In order optimize performance even further, the factory employs a special version of Ray Gralak's PEMPro developed specifically for their test equipment so that they will generate a unique PE curve for each mount and program it into each GTOCP3 Control Box. Simply use the Keypad or your Astro-Physics software (ASCOM V2 driver, PulseGuide or APCC) to turn the PE Correction "on" and you will see results significantly better than our published 5 arc second spec without additional PEMPro runs! However, you may use PEMPro to further refine your PE, if you chose to do so. The 1600GTO features the capability to align at anywhere between 0 to 78 degree latitudes without an optional Wedge; that spans from Antarctica to the arctic circle! The 1600GTO head has extensive milling to keep the basic head weight to about 115.5 lbs (52.5 kg). The head will stand about 4 to 4-1/2 inches taller (depending not the selected Park Position) than the 1200GTO, and most hardware options remain interchangeable. There are new, larger 7.65 inch wide "P" series Saddle and 23 inch long Dovetail Plate choices coming available, and a new larger 24 lb. Counterweight. Another nice aspect of the 1600GTO is that the Rotating Pier Adapter, formerly an option for the 1200GTO, is standard with the 1600GTO.

      For these products we will first refer to our waiting lists, sending invitations to notify people who have registered, then we will assign spare production slots to new customers. Accordingly we have updated our Astro-Physics Telescope and Mount Availability information page and commenced sending out invitations to those lucky people. Company Seven has one last new 1200GTO German Equatorial Mount (from the last production lot) on static display at our showroom. We have not yet decided whether or not to keep it on display and add the 1600GTO alongside it for comparison, or sell the 1200GTO to make room for the 1600GTO. Of course we will prefer to give priority on assigning this last 1200GTO to those who have historically chosen to buy from Company Seven. Either way, the display will continue to be impressive and unrivaled. It is possible that we may be receiving some 1200GTO mounts in trade or on consignment as some customers will want to upgrade their observatory, so this may help customers seeking a more 'transportable' alternative to the 1600GTO.

    • We added additional information to our article Nikon 300mm f/2.0 ED IF and Tochigi Nikon 300mm T2.2, our tribute to these rare and amazing large aperture and super-fast ultratelephoto lenses that remain unrivaled even today. And since photos and text are simply not enough, Company Seven acquired a new Nikon 300mm T2.2 (300mm f/2 - imagine a 6 inch /2 Apo!) lens for our collection, one of only twenty-some made by Nikon, and that too is now on static display in our museum collection. More reasons for you to make the pilgrimage.

    • Commencing delivery to customers who ordered from the Summer 2012 production run of the Astro-Physics 175mm f/8 EDF Apo refracting telescopes. We expect to have all our new AP 175 EDF telescopes delivered to our customers within two or three weeks!

    • Added additional information about the Nikon UV-105 F4.5, a fascinating multispectral lens distributed to most of the world by Company Seven. This rare lens is suitable for work with modern digital SLR cameras for work in the visual to infrared spectrum, but with specialized cameras or sensors or with film cameras and appropriate films the lens permits high resolution work well into the ultraviolet (UV) spectrum - transitioning at 220nm! The lens was originally envisioned for uses including: law enforcement forensic work (popularized by recent television shows), industrial and biomedical applications, as well as uses by artists and the more enthusiastic amateur. The lens is now employed not only in those fields but also studies in: agriculture, environmental monitoring, mineralogy, chemical analysis, surveillance, physics, manufacturing and process control.

    • Made some other minor updates to various pages within our site.

    Changes in January 2012:


    Changes in November 2011:

    • On 15 November the formal public announcement and ribbon-cutting ceremony were held for the MCCM observatory telescope at the Johns Hopkins University Applied Physics Laboratory (JHU/APL) in Laurel, Maryland. This project was commenced in 2007 by the owner of Company Seven with the acquisition of the Optical Guidance Systems (OGS) RC24, a modern 24 inch (0.61 m) aperture Ritchey-Chrétien professional-grade computer controlled telescope complete with Fork Mount, and a 5 meter diameter observatory dome with welded steel base structure. This culminated in 2010 with an agreement to loan the telescope to the JHU/APL for a several years term.

      There was an unusually good omen for the new observatory. As the date of the ribbon-cutting approached the days were more and more cloudy until on the day of the event the coverage of clouds was complete from horizon to horizon. When the event commenced at 7 pm the skies were still completely cloudy. At 8:38 pm, as the ribbon was cut opening the observatory dome, someone called out "a star". We looked to see a small area of cloud cover had thinned just enough to reveal Jupiter, but no other stars or Moon across the sky could be seen. We powered up the telescope and its control systems, opened the dome, then turned the telescope onto the giant planet - now about 49 Arc. Secs. in diameter and about as well positioned as it gets for us on Earth. Amazingly enough, Jupiter remained visible for all to see. Even though the facility had only one eyepiece, a TeleVue 41mm Panoptic providing only a modest 119x, over the next twenty minutes or more Jupiter put on a great show and all who walked up the steps to the eyepiece of the telescope and enjoy that sight.

      Accordingly we have updated our 'MCCM' Observatory Project index page to reflect the announcement and progress of the plans so far.


    Changes in October 2011:

    • added review of Turn Left at Orion: Hundreds of Night Sky Objects To See In A Home Telescope - And How to Find Them, by Guy Consolmagno and Dan M. Davis. This is the newly revised fourth edition now made available in a softcover spiral bound format. This nicely illustrated guide may just be the budding astronomer's best first guide to finding their way through the night sky. It is now available at our showroom or by mail order.

    • on 29 October our fearless leader attended a concert by Sting at the Daughters of the American Revolution (DAR) Constitution Hall, in Washington, DC. He took with him a Leica 8 x 20 BL ULTRAVID compact binocular, a Leica 10 x 42 ULTRAVID HD binocular, and a pocket camera. The seats, even at $120 each, were in the far back of the hall, the top and rearmost seats but directly at the center. He came away amazed again at how Company Seven's technology and teaching can put one in the front row; he wondered how much life have those others, who were not similarly equipped, been missing so far?

    Changes in August 2011:

    • Since we have had so much new work related to sales, installation and support of observatories over the past year, including the work with two large Optical Guidance Systems telescopes we decided to expand upon our mention of this work at our Products & Services index page to explain more about the sales and services we offer involving Astronomical Observatories Design and Installation Services.

      Lunt 60mm and 80mm Hydrogen-Alpha solar telescopes outside Company Seven 13 August 2011 (26,729 bytes)

    • Company Seven apologizes to our fellow astronomers in the mid-Atlantic region, it seems our new Lunt LS80/DSII/B1800/PT/FT Hydrogen-Alpha (Hå) solar telescope arrived on 5 August, and since then the formerly beautiful weekends have turned from clear, sunny and dry to overcast, raining and wet. It was only on 13 August that we were able to sneak the Lunt 80 alongside a Lunt 60mm Double-Stack Hå telescope (LS60/DS/B1200/PT/FT) for brief moments of solar observing between the newly arriving thunderstorm cloud banks.

      Click on image to see enlarged view (446,834 bytes).

      These Lunt telescopes are purpose built solely for studies of the Sun. Our new LS80 model is for display and joins our inventory of Daystar Hå filters too for Saturday solar observing sessions at Company Seven. This telescope provides an 80mm aperture with an 18mm diameter blocking component in the diagonal at rear. These systems filter sunlight so that one sees the Sun as a deep red disc contrasted against the blackness of space. The image of the Sun is brought to focus at a point beyond the focuser. An eyepiece for viewing or a camera for photography can be attached to the focuser.

      The filter components are so precisely made that any change of ambient temperature alters the bandpass, so in order to compensate, a piston attached to the filter housing is adjusted to 'pressure tune' the bandpass by dialing in or out to bring the filter to its best performance setting. With a primary filter alone the bandpass is between 0.7 to 0.8Å (Angstroms) centered at 653nm; so details on the surface of the Sun and surrounding prominences are seen. Ours is among the first of the new Lunt DSII series telescopes indicating 'double stack at the rear' so one can attach a second filter component in the black housing just behind the red collar to further narrow the bandpass to 0.5Å or less. This provides added contrast of details on the Sun's disc and of the more massive ejections and prominences, at times appearing three-dimensional. These are rugged and compact telescopes, easy to travel with. We placed the LS60 alongside the LS80 with 1.25 inch diameter diagonal attached for scale, note the focusers are 2 inch 'FeatherTouch' models with braking made by Starlight Instruments.

      In time Company Seven may develop new sections in our web site featuring the Lunt and Starlight Instruments products at least for as long as we do not provide so much content that it tempts 'E-Tails' to steal our content.



      Optical Guidance Systems 32 inch telescope at George Mason University 27 July 2011 (26,729 bytes)

    • Helping to bring a new Optical Guidance Systems telescope on line; another masterpiece from John Stiles and the team at OGS in Pennsylvannia. This new OGS fork-mounted 32 inch (0.81 m) aperture Ritchey-Chrétien telescope was sold to George Mason University in Virginia by Company Seven and OGS. The Ritchey-Chrétien optics set was made by Paul Jones of Star Instruments; these were originally ordered for this project by Observatory Scope, a defunct Georgia-based company who originally won the bidding but then failed to complete the task. The OGS designed Secondary Mirror Focus mechanism employs a "RoboFocus" for remote control, this is made by Technical Innovations. The optical tube axial port is provided with the well regarded Astro-Physics 4 inch rack an pinion focuser. We will continue to provide assistance to GMU, and will be pretty familiar with this system since it is in effect the big brother of our own OGS 24 inch telescope. The GMU telescope will be completed with the SBIG STX-16803 CCD system, also provided by Company Seven.

      The purpose-built cylindrical observatory building with 6 meter diameter Ash Dome housing the new telescope were designed by GMU and their contractors.

      It was the early discussions for this task, and our offer to acquire and refurbish the Biosphere Observatory telescope as one of the options, that first brought that OGS 24 inch telescope to our attention. It was in time acquired by our owner, and activated late in 2010 nearby in Maryland. So now GMU's telescope is larger than ours by 0.2 meter, and their dome is 1 meter larger in diameter than our Ash Dome. We'll do better with our next telescope - the 'MCCMOv2.0'!

    • Announced Leica Binoculars 'Trade up' Program. A promotion effective 1 August through 31 October 2011 that allows anyone to trade-in ANY BRAND OR MODEL of working binocular for a $200 instant credit against the purchase of 32, 42 and 50mm Leica Ultravid HD binoculars. This is one of the few opportunities to obtain a break on a new, fully US and international warranted Leica product as this is a factory-authorised program available only at authorized retailers including Company Seven of course.

    • Updated our review of a wonderful adjustable-height periscoping pier, the 2011 production Pier-Tech 3. This review now shows one of these newly redesigned piers installed by Company Seven at the private observatory of a client for whom we also installed a new Astro-Physics Model 1200GTO German Equatorial Mount with a Celestron C-14 telescope optical tube assembly, also provided by us.


    Changes in July 2011:

    • Updated the review of a wonderful adjustable-height periscoping pier, the 2011 production Pier-Tech 3. This review now shows one of these newly redesigned piers installed by Company Seven at the private observatory of a client for whom we also installed a new Astro-Physics Model 1200GTO German Equatorial Mount with a Celestron C-14 telescope optical tube assembly, also provided by us.

    • Company Seven updated two reviews of our most popular selling TeleVue telescopes, the 2011 production TeleVue NP101is and the recently upgraded TeleVue NP127is telescopes. Then added an entirely new review of the 2011 production model TeleVue NP101is, the latest of the upgraded Imaging Systems photo-visual telescopes.

      The NP101 and NP101is are the first TeleVue 4" Apos that we rate as the equal of the worlds best in optics and mechanics featuring upgraded focuser that not only manages heavier payloads, but incorporates the Feather Touch® two speed, 9:1 geared focuser pinion assembly. This focuser accepts optional motorized control permitting local control of focus by the user, remote control via wired or wireless, or automated focus control by computer. While the handy NP127is remains the fastest, flat-field Apo telescope in production - also incorporates the Feather Touch® focuser.

      Since TeleVue has made numerous changes to their telescopes over the past year we updated our TeleVue Imaging System Accessories index page so that our customers will be able to better understand which accessory is compatible with which model of current and older discontinued models as well.

    • Company Seven posted a new illustrated article about the Unitron Model 220 - ASTRO-CAMERA. This describes an original Unitron sheet film camera specifically sold for astrophotography, but also capable of terrestrial work with these telescopes. This is among the optional accessories that accompanied the Unitron Model 142, a 3 inch (75mm) f/15 achromatic photo-equatorial telescope acquired for Company Seven's Museum Collection earlier in 2011.


    Changes in June 2011:

    • Posted our illustrated review of the beautiful TeleVue "102 Renaissance", brass 4 inch multi-purpose refracting telescope. Sometimes called the Renaissance 102, this third generation brass telescope of TeleVue is a first-rate four inch aperture telescope that happens to be beautifully made in brass...as striking to look at as through.

    • Added scanned copies of instruction manuals for accessories included with the Unitron Model 142 telescope that Company Seven acquired for our museum collection and display. We already host an article about this Model 142 telescope, and today we added scanned downloadable .pdf copies of the Unitron instruction manuals for both the UNIHEX and for their ASTRO CAMERA Model 220. These are available at our Unitron Notes & Interesting Articles index page. Over time we will add more articles dedicated to some of the more interesting accessories, as we progress with the conservation and cleaning of this telescope.

    • Commenced sending invitations for registered customers to order from the Summer 2011 production run of the Astro-Physics Mach1GTO German Equatorial Mounts that are well underway too, we expect to commence making deliveries of these mounts in July 2011. For these products we refer to our waiting lists, sending invitations to notify people who have registered. Accordingly we have updated our Astro-Physics Telescope and Mount Availability information page.

    • Posted a new article Binocular Care And Service Interval Advice: Suggestions by Company Seven. An illustrated overview discussing the mechanisms that compromise the performance or longevity of binoculars. We provide some tips about preventive maintenance, identifying problems, and what to do when your binocular is damage or in need of servicing.

    • Company Seven posted a new review of one of our most popular selling telescope, the 2011 production TeleVue NP101. The NP101 is the first TeleVue 4" Apo that we rate as the equal of the worlds best in optics and mechanics featuring upgraded focuser that not only manages heavier payloads, but incorporates the Feather Touch® two speed, 9:1 geared focuser pinion assembly. This replaces the prior version NP101 telescope.


    Changes in May 2011:

    • Company Seven delivered another new interesting optical system to NASA. While there are many projects we do not publicize, on 10 May Company Seven delivered another interesting optical system to Goddard Space Flight Center for NASA to fly later in 2011. This is a ruggedized and shock/vibration resistant catadioptric system with all optical components made fully quartz (fused silica), and with superbly engineered and applied high transmission coatings optimized for its designed transmission application. In order to maintain perfect focus at all operating temperatures the construction of the tube assembly and many mechanical components are largely of Invar, an ultra-low expansion aerospace grade alloy.

    • Company Seven acquired a Unitron equatorial refractor telescope to add to our museum collection and display. The basis of this cased set is a Unitron Model 142 telescope, a 3 inch (75mm) f/15 achromatic refractor sold on 20 May 1975. However, this Model 142 equatorial telescope has been upgraded to beyond the level of the Unitron Model 145, a 3 inch Photo-Equatorial telescope, with almost every conceivable option of the day. Not only is this provided with Unitron accessories including the AC powered Clock Drive with an optional AccuTrack Drive Corrector, but it also has a Unitron Astro Camera, a Criterion Coronagraph, and two Unitron Herschel Wedges. The condition of the set is uncommonly good and the documentation that came with it is comprehensive - many days of scanning in literature for our archives are ahead of us! We have placed the telescope on display in our showroom, and added an article about this Model 142 telescope to our on-line 'virtual museum'. Over time we will add more to the article and probably host separate articles dedicated to some of the more interesting accessories, as we progress with the conservation and cleaning of this telescope.

      The caption for the article might be "Our Unitron Has More Stuff Hanging Off It Than Your Telescope".


    Japan Earthquake and Tsunami (19,710 bytes) Changes in March 2011:

    • Posted a special appeal to Assist Japan's Earthquake And Tsunami Victims that struck Japan on 11 March 2011. We have many friends and customers in Japan as well as suppliers to whom our hobby is indebted, so we will assist the citizens of Japan to recover from this disaster. Accordingly we are hosting information about how you too may help, though we are not collecting donations directly, for this effort.

      Prayers may comfort the souls of the departed, but donations of money will more immediately comfort the survivors and might save lives too. We urge you to contact legitimate relief organizations and to contribute, any amount will help. You may donate to assist Japan through this American Red Cross on-line link

    • We added additional information to our article Nikon 300mm f/2.0 ED IF and Tochigi Nikon 300mm T2.2, our tribute to these rare and amazing large aperture and super-fast Nikon ultratelephoto lenses that remain unrivaled even today. This information includes new photographs and specifications of the Tochigi Nikon 300mm T2.2 lens, one of only twenty (20) made by Nikon, in our collection.


    Changes in February 2011:

    • Announced the TeleVue Factory Authorized 20/20 Sale!. Commencing on Friday 4 February concluding on Sunday 17 April 2011, save twenty percent off our normal pricing on all TeleVue eyepieces. Yes, this factory authorized sale includes all the latest TeleVue Ethos and Ethos SX, all TeleVue Nagler series (Type 4, Type 5, and Type 6), Panoptic, Plossl, and Radian. Also included are the TeleVue coma-correcting visual and imaging Paracorr lenses, Barlow lenses.

    • Added new page detailing the Ultra Violet Products Model C-10P, this is the first of our UVP Mini Chromato-Vue® observing cabinets detailed in our UVP products section. These are compact enclosures designed specifically to provide a portable cabinet for the inspection of samples illuminated under ultraviolet emissions.

    • Continued sending invitations for registered customers to order from the Spring 2011 production run of the Astro-Physics 130mm f6.3 Starfire EDF telescopes, and for the 1200GTO German Equatorial Mounts that are well underway too, we expect to commence making deliveries of these mounts in March 2011. For these products we refer to our waiting lists, sending invitations to notify people who have registered. Accordingly we have updated our Astro-Physics Telescope and Mount Availability information page.

    • Added additional information about Zeiss ULTRAFLUAR microscope objectives to our article "Ultraviolet Spectrum Primer". This illustrated article by Company Seven explains the ultraviolet (UV) spectrum as it applies to photographing or imaging objects in the UV. The article explains the UV spectrum including UV-A, UV-B and UV-C. Imaging gear including lenses such as the Nikon Rayfact UV-105 F4.5, films and filters. We will continue to add more information about suitable CCD cameras and films for work in the UV.


    Changes in January 2011:

    • Announced the Spring 2011 production run of the Astro-Physics 130mm f6.3 Starfire EDF telescopes, we are accepting orders for delivery through the Summer. Our Spring production of the 1200GTO German Equatorial Mounts are well underway too, we expect to commence making deliveries in March 2011. For these products we refer to our waiting lists, sending invitations to notify people who have registered. Accordingly we have updated our Astro-Physics Telescope and Mount Availability information page.

    • We kick off the new year by hosting a new article about amazing optics: Nikon Nikkor 300mm f/2 ED IF and Tochigi Nikon 300mm T2.2, our tribute to these rare and amazing 160mm aperture Nikon ultra-telephoto lenses that remain unrivaled even today. This is hosted at our Nikon Notes & Interesting Articles section of our Library.

      In this article we think back to the 1970's and 1980's when Nikon dominated professional 35mm single lens reflex (SLR) camera and lens technology, and their logo was known to almost anyone world-wide. This was a time when a corporation like Nikon would put its best minds to work at developing truly amazing products in addition to those that simply made good commercial sense. Their innovations include producing the the world's first high performance 200mm f/2 telephoto lens, and the world's first and only high performance 300mm f/2 ED IF telephoto lenses, the cousin of the world's first 400mm f/2.8 ED IF lenses. Here we provide a well illustrated overview of the history and development of these lenses, three variants of which are described in this article, complete with Patent papers and other information. We will most likely add more information to the article over time as new information comes to light.

      Yeah, we know Nikon has not made these lenses for years and probably never will do so again, so this has nothing to do with Company Seven earning any income or paying bills. We put great effort to researched, collect, and conserve these lenses because of our respect for the achievements by Soichi Nakamura and Kiyoshi Hayashi. Furthermore, we like to inform and entertain our customers who make it possible for us to stay in business.


    Changes in December 2010:

    • Began to host the first pages of a new section, this describes products sold by Company Seven by UVP - Ultra Violet Products. The UVP company has seventy-eight (78) year long tradition of manufacturing products for industry, government, and academia. Known for decades as Ultra Violet Products Co., UVP manufactures bioimaging systems for for genomic, proteomic and invivo applications. UVP bioimaging systems are used for DNA gel documentation and image acquisition, analysis of gels, blots, fluorescence, chemiluminescence, western blots, northern blots, southern blots, luminescence, colorimetric, chromagenic, densitometry, in vivo and in vitro, plates, and film. While their laboratory instruments and ultraviolet products are employed for academic, pharmaceutical, forensic, industrial and biotechnology applications. These products compliment the well regarded UV capable optics systems that Company Seven's industrial side offers.


    Changes in November 2010:


    Changes in October 2010:

    • Posted updates with photos showing the The MCCM Astronomical Observatory & Telescope. This telescope and observatory have been relocated to Maryland by the owner of Company Seven for the ultimate benefit of science education in our region. The Dome was installed along with the telescope concrete foundation, wiring conduits for utilities (power and signal). On 28 October the telescope Wedge, Fork Mount, and Optical Tube Assembly were lifted into the dome by a large crane. We expect the final adjustments on the system to be completed, with the system ready for service in a matter of weeks.

    • Posted announcement about the newly released 2010 model TeleVue NP127is telescope. The first of these new telescopes arrived at Company Seven on 8 October. We understood the new telescope would have improved color correction, but were pleasantly surprised by the final new production telescopes. The improvements provided with this third generation NP127is include:

      • color correction of this NP127is system has been improved so that it equals the TeleVue NP101 4 inch Apo telescope. The telescopes show no trace of false color, and textbook diffraction patterns even at silly high magnifications on the most demanding artificial star and sub-micron resolution tests that we routinely use to evaluate every newly arrived telescope destined for our customers.

      • the focuser has been completely redesigned, sculpted to form a more beautiful and curvaceous appearance - just like Marlene!. As a part of this process a substantial improvement has been made to the TeleVue FocusMate dual speed geared focusing mechanism replacing this with a 10:1 focuser pinion assembly made for Tele Vue by Starlight Instruments!

      • the front lens cell and lens shade/dew cap have been redesigned; we find this aesthetically and practically an improvement. With the lens shade extended the telescope is about the same overall length as its predecessor, but it no longer appears so 'stubby'. With no machined lens cell protruding back beyond the extended lens shade there is a greater span of tube length onto which one may attach options.

        Our overview of this telescope is now on line at TeleVue NP127is 2010 Model. Feel free to contact Company Seven for additional details, or to place an order for delivery as these become available.

    • Posted new review about the Baader Planetarium Methane (889nm) Filter a specialized imaging filter stocked at Company Seven. The Methane (CH4) filters have been popularized by numerous space missions for imaging gaseous objects including Jupiter, Saturn, Uranus, Neptune, Earth, and our Sun. This is a 1.25 inch threaded filter designed for CCD imaging with suitable infrared sensitive telescopes and cameras. Passing only an 8nm wide sliver of light in the infrared, this filter is not suitable for visual use.

    • Expanded our discussions about Nikon, focusing more on the history of Nikon with mentions of the lenses that particularly highlight the history of optical innovation by this company.

    • Added additional information to our article "Ultraviolet Spectrum Primer". This illustrated article by Company Seven explains the ultraviolet (UV) spectrum as it applies to photographing or imaging objects in the UV. The article explains the UV spectrum including UV-A, UV-B and UV-C. Imaging gear including lenses such as the Nikon Rayfact UV-105 F4.5, films and filters. We will continue to add more information about suitable CCD cameras and films for work in the UV.


    Changes in September 2010:

    • Posted new article "Ultraviolet Spectrum Primer".

    • Posted the first pages of a new section describing our Nikon special products; items of limited production not routinely available in the Americas. The index page features an overview of Nikon including some history of this company. Of course we hit on the highlights pointing out some of their most astounding optical lenses, and telescopes too.

      The first item we feature is the famous Nikon Rayfact UV-105 F4.5 Lens that is offered in the Americas through Company Seven by special order. This lens bears the 'NikonRayfact' designation, but it is a current Nikon production lens that replaces the original UV-Nikkor (PN 1453) that was introduced in September 1985. The UV-105 lens is an exceptionally sharp 105mm f4.5 conventional lens with macro (2:1) capability too. However, this lens is most acclaimed for its usefulness from 220nm in the ultraviolet up through the visual spectrum and into the near IR at 900nm. This this is a preferred lens for forensics, medical studies, electric discharge studies, research, or for the more dedicated amateur who seeks to explore portions of the world invisible to the eye. This lens is provided with the Nikon F mount and as such can be attached onto any Nikon SLR film or digital camera, or onto a Bellows or other fixtures. We will gradually describe more and more of the limited production Nikon products as we develop our Nikon section on line.

      This Nikon UV Lens is complemented by our afused silica Long Distance Microscopes that can provide resolution in the visual and UV spectrum down to the sub-micron level.


    Changes in August 2010:

      Much has been going on at Company Seven over the recent months, but since we are foremost showroom oriented and not primarily an 'E-tail' based shop and since our people have been spread thin overseas on other work we do, we have not been able to provide much attention to our Internet site as we would like to. You can contact or visit our showroom to see these, and in time we may post detailed illustrated reviews of these 'hot' new products on line. But for a taste of some of our most favorite recent news here goes:

    • Announced we are accepting new orders for the new 305mm f3.8 Riccardi-Honders Astrograph, a telescope designed primarily for wide area photography. This is the first production lot of the new high performance 12 inch telescope. The system includes a 3.5 inch diameter focuser, Dewcap (Lens Shade), Dust Cover, pair of Mounting Rings, and Carrying Case. Company Seven will offer an optional Airline Transport Association Approved (ATA) shipping case for this instrument. Announced on 18 April 2009, the prototype has been shown at some events and taken numerous amazing astrophotos. This telescope features diffraction-limited performance over a huge three (3) degree field, which is ideal for capturing large faint nebulae over a wide wavelength range. The design has essentially perfect color correction from 400 to 1000 nanometers (UV to IR), is fully corrected for all five Seidel aberrations (spherical, coma, astigmatism, field curvature and distortion), as well as longitudinal and lateral chromatic aberration. Being a nearly 70 lb (30 kg) working payload, this will require a suitable mount to do it justice. Although it was shown installed side by side with the Astro-Physics 12-inch Maksutov on the massive Astro-Physics 3600GTO 'El Capitan' mount, we will prefer the Astro-Physics 900GTO or Astro-Physics 1200GTO mounts for transportable operations.

      The Pricing of the instrument set is $17,500.00. We have updated our availability information for this product on line reflecting we are accepting orders for deliveries starting in Fall 2010 and continuing into 2011.

    • Announced we are accepting new orders for the Astro-Physics 3600GTO 'El Capitan', a high performance German Equatorial Mount. Announced in October 2007, the mount features a working payload capacity of about 250 lbs. / 114 kg. It is transportable, with Astro-Physics recommending at least two able bodies to attend to it. This mount is designed to follow several other Astro-Physics 900GTO and Astro-Physics 1200GTO mounts that have performed remarkably well in climates as harsh as Antarctica! You will like what you see and read about these mounts.

      The Pricing has not changed. We have updated our availability information for this product on line reflecting we are accepting orders for deliveries starting in late October and continuing into the Fall 2010.

    • We made available at our Questar Library the complete "QUESTAR 700", a moderate resolution scanned copy of an original complete twelve (12) page typed instruction manual for the Questar 700 ultra telephoto lens as was provided with each new lens sold from 1979 up to when the lens was discontinued in 1986. Someday we may add one of these lenses to our Museum display. Content Copyright 1979 Questar Corp. Scanned copy of original from Company Seven's Archives, hosted by permission.

    • We completed an illustrated article "Unitron Model 114 - 2.4" Achromatic Telescope" describing the telescope that was acquired and is now on permanent display in our collection. This addition helps to build on our actual and 'virtual museum'. We provide an overview of the history of Unitron telescopes including where they were made, and ultimately how the marketplace changes led to their demise.

    • Company Seven was granted permission to scan and host "The Green Lights Are Flashing For Johnny Carson", an article by Gilbert Millstein with photograph by Curt Gunther in the 8 June 1963 issue of the weekly TV Guide Magazine. The late Johnny Carson came to the hobby of astronomy and accumulated several telescopes including a Unitron Model 114 60mm Achromatic Refracting telescope, pictured in this interview. Over his tenure as host of "The Tonight Show" and in other ways he popularized the science of astronomy. He was formally recognized by the professional astronomy community when the asteroid "3252 Johnny" was named after him. This article is protected by Copyright, we obtained permission from TV Guide Magazine, LLC to scan and host this article from the original in our archives for the benefit of our readers and for display alongside the Unitron 114 (mentioned below) in our museum collection. Please do not distribute this without permission. Download size is 5,675,333 bytes as an Acrobat Reader ".pdf" file.


    Changes up to July 2010:

      Much has been going on at Company Seven over the recent months, but since we are foremost showroom oriented and not primarily an 'E-tail' based shop and since our people have been spread thin overseas on other work we do, we have not been able to provide much attention to our Internet site as we would like to. You can contact or visit our showroom to see these, and in time we may post detailed illustrated reviews of these 'hot' new products on line. But for a taste of some of our most favorite recent news here goes:

    • We acquired our first Unitron achromatic refracting telescope for permanent display in our museum collection. Ours is a Model 114, the 60mm x 900mm focal length telescope with the matching alt-azimuth mount and wood tripod. The instrument merits a place in our collection since these were among the best made and most desired (if not affordable) first astronomical telescopes for many who grew up through the 1950's and 1960's. We also recall one of our favorite customers, Johnny Carson was drawn further into the hobby in the early 1960's with his Unitron 224. This telescope is uncommonly complete, with few signs it was ever used (unfortunately for the owner?) and with the wood carrying case, and UNIHEX multiple eyepiece holder. The system has been cleaned and added to the display at our showroom. We intend to write about this telescope, hosting it at our 'virtual museum'.

    • Posted updates regarding the status of The MCCM Astronomical Observatory. This telescope and observatory has been acquired and since relocated to Maryland by the owner of Company Seven for the ultimate benefit of science education in our region. The primary goal remains to provide local elementary and junior high school age children with the occasional opportunity to look through the eyepiece of a notable telescope and wonder at those amazing sights that inspired us to pursue science.

      We have signed an agreement that will result in the installation of the The MCCM Astronomical Observatory in Maryland. A formal announcement will be forthcoming. Note, all of this has been accomplished with not a single dollar being donated (even in response to our invitation), with no public funding (even though desired by them, local governments have become cash strapped and could not assist), and with no formal organizing effort. The final arrangement for the operation of the observatory makes even better sense than simply donating it to one or another school district since our choice will provide years of continuous competent support of the observatory, and development of outreach programs.

      We are grateful to Doug Humphrey and to John Stiles the owner of Optical Guidance Systems (who built the telescope). This might not have happened without the help from Doug, he provided sound advice and a warehouse in which to stage the telescope and parts of the observatory while we and John worked to put it back into service. And of course we are happy to be working with the organization that will host the observatory, but more about them later.

    • Added a new page to our Fujinon binoculars section describing the 7x 50 FMTR-SX binocular. This pretty well completes our goal of providing reviews for our customers explaining the better Fujinon 50mm binoculars.

    • Added new information at our Questar index page explaining the development and production of the QUESTAR 700 ultra telephoto lens and the Questar 12 telescope. Both of these instruments were announced in 1976 but are no longer in production. This includes the posting the patented optical design of the QUESTAR 700 at our Questar original patents section.

    • Added information and more recent illustrations to our Airline Transport Association Approved (ATA) shipping cases description page. This page describes and shows examples of the custom transport/shipping cases offered by Company Seven for the protection of telescopes, mounts, and other sensitive equipment.

    • Added more recent examples of findings to our in-house quality control description page. This explains another of the reasons why Company Seven remains unique in our community: our quality control, testing, and certification services. We periodically will add to this page as we receive telescopes that have unusual discrepancies that we may find amusing. OK, we're having some fun here.


    Changes in May 2010:


    Changes in March 2010:

    • Added additional section and articles to our on line Questar Archives. This includes copies of the original patents pertaining to the development of the Questar 3-½ telescopes. Also posted the "Questar" booklet, a moderate resolution reprint of original Questar 28 page illustrated booklet provided with new Questar telescopes, dated May 1954. File is 2,387,280 Bytes (in Acrobat Reader ".pdf" format). This copy was scanned from the original in Company Seven's Archives.

    • Over the past two months we added several new Orion telescopes to our showroom display including the new Orion XX-14, a 14 inch aperture f4/9 truss tube Dobson style telescope. The XX-14 now sits alongside the popular XX-12 in our showroom; these are among the best well thought out and largest easily one man transportable reflecting telescopes made - and for the price nobody can touch them for best value. The XX-14 brings with it more than double the light gathering power of our very popular SkyQuest™ XT10 IntelliScope™ 10"/25.4cm f4.7 Dobson style telescopes and so the XX-14 provides a logical and transportable next step up for our customers who have developed "aperture fever". Showing actual fields of view of up to 1.45 degrees of sky (with TeleVue's 31mm Nagler Type 5) the XX-14 can show nearly four times the area of sky (with a 6.7mm Exit Pupil) than our popular Celestron or Meade 14 inch catadioptric models, and at about 1/3 the cost of these catadioptric telescopes.

      We also added the Orion EON 80ED, an affordable (~$600) compact and multipurpose f/6.3 apochromatic refracting telescope that has become quite a popular and handy compact telescope at Company Seven. With actual fields of view with eyepieces of up to 5.4 degrees at magnifications as low as 12X; this is suitable even for panoramic work, wide sky applications including use as a superb finder telescope. Furthermore, its overall good qualities allow higher magnification work that provides clearly identifiable views of the major changing features on the planets.

      Being so impressed with the value of the EON 80ED we also put on display the EON 120 ED, a 120mm (4.7 inch) aperture f/7.5 apochromatic refractor. The EON 120ED with its noteworthy increase in light gathering power over most 4 inch Apos, but selling for about 1/2 the price tends to make up with size what the lens may lack in overall performance and as such will attract many people back to Apos who seek a 4" Apo but can not afford our top line 4" apos. Furthermore, at low to mid magnifications this ~$1800 telesocope brings in visual deep sky images better than even our better 4" apos owing to the 22% increase in light throughput of the 120mm lens compared to most better 102-105mm class apos. And at f/7.5 the telescope remains handy, and can work well with a broad selection of less costly eyepiece designs even though most customers buying this telescope do recognize the value of investing in premium eyepieces. The EON 120 ED includes hinged Hex mounting rings and a V series mounting plate; these make it suitable for many applications even as a guide telescope or it can easily accept an optional photo-guide telescope.

      The EON 80ED and the EON 120ED are fully machined well thought out telescopes. Each is provided with a 2 inch diameter Crayford style focuser, with dual speed geared focus control - and the entire focuser can be rotated to facilitate composition when imaging with film/digital or CCD cameras. An optional field flattener lens (for imaging applications) is among the available options. Each of these telescopes is furnished in a nicely made, comparatively light weight metal-clad and foam lined carrying case.

    • The Spring 2010 production run of the Astro-Physics 130mm f6.3 Starfire EDF telescopes is sold out. Our Winter 2009-2010 production of the 1200GTO German Equatorial Mounts are sold out.

      Company Seven is now accepting orders for the portable Mach1GTO mounts. These will be completed for delivery between April and July 2010. We have been working on the custom design of a new Airline Transport Association Approved carrying/shipping case for the Mach1GTO head and accessories since September 2009! But it is only in recent days after making several prototypes that we have settled on the optimum arrangement for this new case. We hope to have the first case completed in another week or so by mid March. Once we sort out what our costs have been to get this far then we will be able to quote a price for this new product.

      We updated our Astro-Physics Products Availability information page to reflect this and other developments.


    Changes in October 2009:

    • The sole 2009 production run of the Astro-Physics 900GTO German Equatorial Mount is sold out at the factory. However, Company Seven has one new uncommitted 90GTO mount available from this Fall 2009 production run for sale, these will arrive in November or early December. Furthermore, Company Seven is now accepting orders for the larger 1200 GTO mounts for delivery between late December 2009 into April 2010. We updated our Astro-Physics Products Availability information page to reflect this and other developments.

    • 20 March 2010 Event: Company Seven Supporting NASA Sun-Earth Day educational activity. This year's theme will take us on a journey into the heart of the electromagnetic force.

    • Posted updates regarding the status of the former Biosphere 2 Astronomical Observatory, since relocated to Maryland as we work to establish our own Astronomical Observatory to promote science education for primary and middle school children. We explain how we are also in discussions to house the telescope nearby Company Seven at a research laboratory.


    Changes in September 2009:

    • Added another example to explain why Company Seven performs in-house quality control acceptance testing and evaluation of new incoming telescopes. Today we added interesting test results of 16 inch primary mirrors that failed our evaluation process this month.

    • 25 & 29: In April of 2009 Company Seven passed the 29th anniversary of our founding as a legally licensed tax paying business in 1980. In 1980 Company Seven was originally established at a business location in Bladensburg, Maryland about a 25 minutes drive south of our current location. Now we celebrate having opened our first full time dedicated telescope store on 1 October 1984 at 930 Fairlawn Avenue in the the old 'Laurel Center'. We have since operated a showroom in Laurel continuously for 25 years, and since October 1986 we have been in our present showroom at 14300 Cherry Lane Court in Laurel.

      When we opened there was a telescope shop operated by an enthusiast ("Tuthill the astronomer's friend", etc.) in almost every major city. However, by 2009 Company Seven finds itself among the very few and longest lived competent astronomical telescope oriented specialty showrooms left in the Americas. Throughout this time while others promoted themselves ('bigger', 'cheaper', 'snazzier', 'order now on-line') we outlasted most of them by simply promoting our hobby. We have helped to establish astronomy clubs in schools and communities in the USA and overseas as well. The name 'Company Seven' is synonymous with uncommonly high standards of integrity and competence, and for unflinching loyalty to those who have elected to associate themselves with us.

      We are not sure who should thank who the most: our customers thanking us or us thanking our customers but every new acquaintance has been a privilege for us and we are happy to know we can travel the world and meet friends who share our passions. Thank you!

      Unfortunately for us there is too much work to do, and so do not look for any parties or back slapping at Company Seven this month.


    Changes in August 2009:


    Changes in July 2009:

    • Posted updates regarding the status of the former Biosphere 2 Astronomical Observatory, since relocated to Maryland as we work to establish our own Astronomical Observatory to promote science education for primary and middle school children. We explain how the telescope was shown at NEAF, an astronomy show this Spring, and how the telescope is being updated to represent the state of the art in RC tech.

    • Posted "Introducing The Questar 12", a moderate resolution reprint of original two-third page advertisement from October 1979 issue of Scientific American magazine. Content Copyright 1979 Questar Corp. Scanned copy of original from Company Seven's Archives.

    • Announced the sole 2009 production run of the Astro-Physics 900GTO German Equatorial Mount. We updated our Astro-Physics Products Availability information page to reflect this and other developments. Company Seven is accepting orders now for the 900 GTO for delivery from August to about October 2009.

    • Posted review of Baader Color Filter Set, 2 Inch Diameter. This selection of filters include lighter and darker variations of red, green, yellow and blue in 2 inch diameter (50.8 mm) thread-on housings. These are particularly desirable for:

      • use on telescopes with longer focal lengths on the order of >2,800 mm, where 2 inch diameter eyepieces may make sense when viewing the entire Moon or planets,
      • use with binocular viewing attachments with two inch diameter eyepiece holders,
      • with 2 inch diameter nosepiece or field fittings,
      • tacking with other color or nebular filters to narrow the band pass. And for special effects or compensation when imaging with film or CCD cameras.

    • While working on our Baader filters section we expanded our review of Baader Oxygen III IR Cut 8.5nm Narrowband CCD/Visual Pass Filter. The Baader Planetarium has developed several of the most precisely engineered very narrow bandpass Nebula Filters, and this Oxygen III IR (Infrared) Cut is our best 8.5nm Narrowband Pass filter. Evolved from the original Oxygen III filters, this is made with features that are desirable for CCD imaging as well as for visual applications.

    • On 15 May Leica Camera announced Save MORE Green a new Binocular $350 Rebate program. This provides a rare discount in the form of a $350 rebate directly to the customer from Leica Camera, Inc. after buying any new full size Leica Ultravid HD or Ultravid, Geovid or Geovid HD* Binocular between 15 May and 30 September 2009 from Company Seven, an Authorized North American Leica Retailer. This $350 program was organized since the original program (ending last month) was never well advertised, or announced in a timely manner, and was too limited - so Leica simplified and made it even better!

      * The original announcement included the Geovid HD models however, Leica later issued a correction notice stating these would not be in the rebate. As a tangible expression of their regret Leica agreed to honor rebates for Geovid HD but only of sold by Company Seven through 25 May.

      Save MORE Money!

      To claim your rebate simply fill out the Mail in rebate redemption form, include a copy of the Company Seven sales receipt along with a completed copy of your product warranty registration card (included in every new Leica product box), then mail it in.


    Changes in April 2009:

    • Posted new illustrated article Accessory Cases: Suggestions by Company Seven explaining why accessory carrying cases are really important and with a discussion about what cases we do recommend and some don'ts too.

    • Posted review of Star Testing Astronomical Telescopes: A Manual for Optical Evaluation and Adjustment, Second Edition. A hardcover book written by Harold Richard Suiter. Released this month, this is The Bible of telescope star testing and adjustment. This continues the fine tradition set by the first edition, but this adds even more information and presents it in ways that are more readily comprehended by a broader readership. It is a great choice for those who wish to better understand their telescopes, and possibly improve the performance of that telescope. Company Seven recommends this title for those persons who have decided to buy an astronomical telescope, or for those who are now considering the choice of astronomical telescope. This can be most helpful when you receive a new telescope since it will teach you how to perform a simple "Star Test", a test method that can be used at the observing site, so that all the problems that impact on a telescope's optical performance can be diagnosed. And since most telescopes are roughly handled during shipping and they often arrive out of proper alignment, "Star Testing Astronomical Telescopes" teaches one how identify if a telescope is out of adjustment ("collimation"), and it will provide insights into how to remedy it.

    • Posted our review of the Leica GEOVID 8x 42 and 10x 42 BRF distance measuring binoculars. These combine precision optics with laser range finder to not only see distant objects in great detail but also to know their distance from you.

      Leica Geovid 42

    • Announced the Leica GEOVID LUX 8x 56 BRF Range Finding /Data-Voice Transmitting Binoculars. A cousin of the innovative Leica GEOVID series of range measuring binoculars, these combine precision light gathering optics with an integral electronic communications module and a sophisticated system of prisms to enable a totally new form of audiovisual communication. Besides viewing distant objects the user of these binoculars can also talk to other binocular users via a headset.

      Using light waves the LightSpeed technology transmits voices in the field of view of the binoculars up to a distance of 1-½ miles (2-½ km) crystal-clear, without any interference, day and night. Even data such as text or images can be fed in via the USB port and transmitted at a rate of up to 1 Mbps. This development has evolved from a cooperation arrangement with the well-known secure electronics development company in the USA. This form of bug-proof communication offers special police and military units a wealth of tactical advantages. The extremely compact yet powerful LEICA GEOVID LUX 8x 56 also has further application potential in stalking, industry and rescue services. US and allied governments agencies should contact Company Seven to obtain our DLA or ORCA information.

      What will they think of next?


    Changes in March 2009:

    • On 3 March Leica Camera announced Save Some Green a new $250 Spring Rebate. This provides a rare discount in the form of a $250 rebate directly to the customer from Leica Camera, Inc. after buying any new Leica Ultravid HD 8x or 10x 42mm Binocular between 3 March and 30 April 2009 from Company Seven, an Authorized North American Leica Retailer.

    • Started work on an entirely new section describing the high-technology superbly well engineered tripods and other accessories made by Particle Wave Technologies. Company Seven particularly recommends the Pinnacle and Monolith series tripods for the most demanding (and more affluent) customers who buy mounts including our Astro-Physics GTO series, Losmandy G-11 and Titan mounts. We finally came around to write about the DDCAP desiccant containing covers for telescopes even though we have been selling the Astro-Physics engraved version (P/N PWDDC2) since 2005. We will add more and more to this section over coming weeks, including reviews of our experiences with these products.

    • Posted announcement at Company Seven's Astro-Physics Telescope and Mount Availability page that we are now accepting orders for the Astro-Physics Mach1 GTO Go To computer controlled mount. We also completely revised our write up of the Mach1GTO to reflect latest news, and choices of options including the custom tripods made by Particle Wave for Company Seven. The article about this mount now goes into more advice about how to pick the components necessary to make a complete system.

    • Posted our long overdue write up about the Orion DeepMap 600, a durable folding plasticized Star Chart. This is among those indispensable publications that Company Seven recommends to those who are interested in learning their way around the night sky. Steve Peters, the editor of DeepMap 600, conceived of this chart of the night sky geared for customers who are new or moderately experienced to the hobby and who buy a telescope or binocular and now seek out what to see and when. Fully color illustrated, the DeepMap 600 shows the positions of more than six hundred of the finest celestial objects visible from the Northern Hemisphere. Each of these objects are plotted on a giant 33 x 21 inch full-color star chart by world-renowned celestial cartographer Wil Tirion. The chart is easy to read, and you will see more of the night sky when reading this with an optional red flashlight. But what really makes this star chart invaluable is its convenience, it folds "accordion style" into a thin pocket-size 4-¾ x 10-½ inches format - just like a road map!

      To learn more about how impressive this handy chart is, browse the DeepMap's more than 600 contents: Deep-Sky Objects Catalog, Double and Multiple Stars, Steve Gottlieb's Top Variable Stars. These can be found in our Library Orion Notes & Interesting Articles page. For the inexperienced beginner we also recommend acquiring the large David H. Levy Guide to the Stars Planisphere.

    • Much new Leica activity at this site, this was motivated by the arrival of a really amazing new APO-TELEVID spotting telescope from Leica Camera AG. We posted a detailed review of the Leica APO-TELEVID 82 Spotting Telescopes that we are finally stocking. This is not a rehash of manufacturer literature, instead Company Seven waits to evaluate new line production samples firsthand before we decide whether or not to offer them; this may explain why we are often among the last retailers to market newly announced products - we wait until they are a reality. So this review is based on direct experience, and is a well illustrated article describing this state of the art durable spotting telescope. We also explain it's first new eyepiece the VARIO 20 - 50x WW ASPH a Aspeheric wide angle zoom lens with continuous 60 degree apparent field of view. This new VARIO eyepiece is to be followed by a new 32x WW and by a VARIO 20 - 60x Zoom. We review and explain the optional Leica APO-TELEVID 82 Ever Ready Case pros and some cons too which we conveyed to Leica Camera AG. In these economic hard times this may be out of reach for most mere mortals, but we can at least wonder about this incredible accomplishment of technology.

      Also added on our site an improved Leica Accessories for Binoculars and Spotting Telescopes index page. This links to several new articles: Leica Binocular Tripod Adapter, Polarizing Filters for the TELEVID, UV Protective Filters for the TELEVID, a well illustrated discussion of the brilliantly engineered and simple to use Leica Digital Camera Adapter used for 'digiscopy' (or 'digiscoping') with compact digital cameras or cell phones ('phonescopy'?). Of course, those demanding the best results with digital or film SLR camera can use the Leica SLR Photographic Camera Adapter.

      While we were adding information about the new Leica APO-TELEVID 82 we dramatically revised and expanded our reviews of the Leica Leica Binoculars. And unfortunately, we also revised Leica Pricing section to reflect 1 January 2009 changes and new products.

    • Added new page describing a new accessory we are offering for Telrads sold by Company Seven, the 2 and 4 Inch Riser for the Telrad Sight. This is an insert that is bolted onto the Telrad Sight Base adding height so that the sight radius clears obstructions on telescopes (dew shield/lens shade, mounting rings, etc.). For use with stage lighting, this can place the Telrad higher off the heat generating surface, or put the Telrad Sight window at a more convenient orientation for the technician.

    Changes in February 2009:

    • Posted updates regarding the status of the former Biosphere 2 Astronomical Observatory, since relocated to Maryland as we work to establish our own Astronomical Observatory to promote science education for primary and middle school children.

    • Posted announcement by SBIG of the new AllSky-340 CCD System, their third generation of imaging system that permits the continuous acquisition of high quality 180 degree views of the sky. Originally the AllSky camera concept was developed so that remotely operated astronomical observatories could monitor the changing sky and weather conditions. Since their introduction some remarkable accomplishments have been made with these instruments including the detection of meteors streaking across the sky; the images from these first generation systems were so good that scientists could use the data gathered by several of these systems in adjoining states to determine the trajectory and other information about these alien visitors!

    Changes in September 2008:

    Changes in August 2008:

    • Published prices for the new Astro-Physics 3600GTO 'El Capitan' high performance German Equatorial Mount. Announced in October 2007 and in production throughout most of 288, the mount features a working payload capacity of about 250 lbs. / 114 kg. It is transportable, with Astro-Physics recommending at least two able bodies to attend to it. This mount is designed to follow several other Astro-Physics 900GTO and Astro-Physics 1200GTO mounts that have performed remarkably well in climates as harsh as Antarctica! You will like what you see and read about these mounts.

      Pricing and availability information for this product are now on line, and we are accepting orders for deliveries starting in late September and continuing into the Fall 2008. It is planned that Company Seven will order one for display in our showroom and so you will be able to see it here. However, we are not certain how many more of these mounts will be made in the near future, so we encourage those who seek a premium mount at an unrivaled price order from this current production run.

    Changes in July 2008:

    • Posted updates regarding the status of the Biosphere 2 Astronomical Observatory and our plans to relocate it to Maryland to establish our own MCCM Observatory.

      For readers interest, and to aid clubs who plan to build an observatory we added another Image Gallery illustrating the Disassembly of the Biosphere 2 Astronomical Observatory Telescope and Dome from 22 to 25 June 2008. We then loaded the facility and transported it to Maryland, arriving on 27 June. The shipment was unloaded into a storage facility on 30 June.

      So now we own and posses the Observatory telescopes, Dome, facilities, blueprints, and images that document this process. This documentation should make the disassembly and reassembly go much more quickly and uneventfully.

    • Posted the first several pages of a new product line at Company Seven. The US based manufacturer Pier-Tech, Inc. has engineered several remarkable solutions for those who need a professional quality Observatory but at a cost that most amateurs can justify. Company Seven has been recommending the product line to some of our customers, even before we agreed to distribute them. In particular we are drawn to the Tele-Station series of observatories with their sliding roof arrangements, and also to their series of Piers including motorized elevating models. We are also gradually adding drawings and instruction manuals for Pier-Tech products at our Pier-Tech 'Notes & Interesting Articles' page.

    Changes in January 2008:

    • In January 2008 Company Seven decided to acquire a used Criterion RV-6 Dynascope. This is a 6 inch f/8 equatorial reflecting telescope originally sold new in December 1962. It is uncommonly complete and original, with original sales invoice and some documentation. The RV-6 represents to us one of that class of amateur telescopes that from the 1950's into the 1970's gave many amateurs their first good glimpse of the celestial wonders, and inspired the passion in us for the hobby. We consider this class of telescope to be so significant that we have incorporated it into our Museum Collection, and now display it alongside an original Celestron 8 from the 1970's and one of the last well made 8 inch f/6 equatorial reflecting telescope from the 1980's a Meade Model 826C.

      In keeping with our goals of conservation and documentation we have prepared an article Criterion RV-6 Dynascope: these introduced many of us to visual astronomy. The article describes the RV-6 acquired by Company Seven, the RV-6 as it changed over the decades, and some history of the Criterion Manufacturing Co. who made this telescope, and provides insight into the evolution and marketing of these types of instruments from the 1950's through the peak of the Apollo space program, and into the 1980's. The telescope is likely to be conserved and not restored to like new, but over time as we learn more about it then we will edit the articles to share the information.

      Furthermore, in a rare collaboration we have arranged permission to use images taken by Tom McDonough of the restoration of a Criterion RV-6 at Criterion RV-6 Dynascope Restoration Gallery. This was a lot of hard work but for a subject close to the heart, it is worthwhile.

    • Posted article about the new Baader Planetarium U-Filter (UV & Venus Filter). Nicknamed "UG11xx" by some in the photo industry, the BPU2 is a specialized UV pass filter made only in 2 inch diameter for use on a telescope or UV capable lens attached to a webcam/CCD, digital SLR, or other sensor. It has produced some remarkable images of Venus, the Sun, and word is spreading fast among amateur and professional photographer who are discovering the world of UV imaging thanks to sensitive digital SLR cameras.

    • Posted a new article in our Questar Library section. The Questar 3-½ Star Chart & Moon Map provides an illustrated description of the beautiful devices that have since 1954 been recognized as trademark examples of the innovation and convenience that is the Questar telescope. We also explain how these may be employed to facilitate navigating the night sky and the Moon.

    • Updated our TeleVue Product Prices page to reflect the end of the TeleVue Factory Authorized Sale - "13/13", this was a successful and rare opportunity for people to have meaningful savings on their purchases. Note however the TeleVue Factory Authorized Telescopes 10% Price Reduction that provides a 10% reduction in prices for all TeleVue telescope sets, optical tube assemblies, and the spotting scope package remains in effect for the time being.

    Changes in December 2007:

    • Announced the TeleVue Factory Authorized Telescopes 10% Price Reduction that provides a 10% reduction in prices for all TeleVue telescope sets, optical tube assemblies, and the spotting scope package. For detailed price listings please read our TeleVue Product Prices page.

    • Added additional information to our Geochron World Clock section. And on Technical Info page we feature images of a custom Cherry wood Boardroom Model made by Geochron for the owner of Company Seven. Also added additional information about how these units are constructed. Published an article at Geochron News to discuss the change of ownership where Geochron Enterprises Inc. was sold to an investor group, and the resulting relocation of the factory from Redwood City, CA.

    Changes in November 2007:

    • Added the Fujinon 10x 70mm MT-SX and the Fujinon 10x 50mm FMTR-SX binocular to our Fujinon Binoculars section. This pretty much completes our reviews of their 50mm to 70mm, and some 150mm aperture models - just in time for Comet Holmes 17P!

      Incidentally, the Fujinon 10x 70mm MT-SX binocular illustrated by us in our review actually FAILED Company Seven's in house inspection process, and it was returned to the manufacturer. Look at the image, can you find the anomaly? We are amused that most E-tailers never even see the box, while a few other shops claim they check what they sell yet few return anything to the distributor. Now, where will you buy your own binocular or telescope?

    • Completed and posted article describing the Piggyback Mount for Questar 3-½ Astronomical Models. This is another one of the numerous specialized accessories developed by Questar decades ago when they were pretty much alone in providing such comprehensive solutions for so many pursuits in the hobby.

    • Completed and posted article describing the optional Losmandy GPS, a receiver that is made to attach to the control panel of the Losmandy Gemini mount control system to automatically provide the system with location, date and UTC Time.

    • Reverted the Company 7 index page to read Eastern Standard Time.

    Changes in October 2007:

    • Published a preview of a new coming high performance German Equatorial Mount: the Astro-Physics Model 3600GTO German Equatorial Mount. Nicknamed 'el Capitan', this mount features a working payload capacity of about 250 lbs. / 114 kg. It is transportable, with Astro-Physics recommending at least two able bodies to attend to it. This mount is designed to follow several other Astro-Physics 900GTO and Astro-Physics 1200GTO mounts that have performed remarkably well in climates as harsh as Antarctica! You will like what you see and read here. Pricing and exact availability have not yet been determined so we are establishing a wait list of candidates for this product.

    • We produced a detailed and well ordered series of articles explaining and illustrating the NP127is, TeleVue's 5 inch Imaging System telescope, and their Imaging System collection of accessories. The Imaging System (or 'is') was introduced in the Spring of 2006 consisting of a selection of new accessories developed by TeleVue specifically to complement their 'is' series telescopes including: Telecompressor or Field Corrector lenses, adapters for a variety of CCD and film imaging uses, the Focusmate™ two speed focus mechanism with control options including digital readout, remote control, and more. While intrigued, we were simultaneously disappointed by TeleVue's decision to drop the original TeleVue NP127 5 inch Apo from production. And we held concerns that some that some of the 'is' accessories resembled poorly executed afterthoughts. Furthermore, TeleVue made a decision as a manufacturer to promote only a handful of E-Tailers as 'featured dealers'; this practice while not unprecedented in this industry undermines what remains of the few competent, service oriented specialty telescope showrooms. So in 2006 and into 2007 Company Seven determined there was no need to divert our resources to support the 'is' effort.

      Over 2007 our opinion of the 'is' accessory products changed as we observed the system become more refined and expand into a more comprehensive and better performing solution. And frankly, several of these telescope are just too good not to feature for our clientele. And so in the interest of supporting C7's customers who are buying 'is' telescopes, we made the effort to demystify the system. Writing these illustrated articles was a bit of a Herculean task since the system is at first glance confusing, and even the initial materials provided to us by TeleVue were simply overwhelming. Regardless, our result will be helpful to our customers.

    • Posted new articles of historic interest: Original Leather Case for the Questar 3-½ Telescope describing the English made saddle leather case provided by Questar with their new 3-½ telescopes sold from 1954 to 1962. We also completed Leather Case For Questar 3-½ Telescopes 1962-1970s describing the rigid leather case provided by Questar with their 3-½ telescopes sold from 1962 into the 1970s. Both cases illustrated are in Company Seven's Museum Collection.

      And another article that is more relevant to today describes the Deluxe Leather Case which may be ordered as an upgrade in place of the standard Vinyl-Clad Case when ordering a new Questar Questar Standard or Duplex astronomical telescope. The leather case is provided as part of the standard equipment with the limited production Questar 50th Anniversary Model telescope.

    • Announced the TeleVue Factory Authorized Sale - "13/13" that provides a 13% Savings for 13 Weeks from 1 October through 28 December 2007 at Company Seven! This event celebrates the release of the TeleVue 13mm Ethos Eyepiece and it applies to ALL their other highly desirable eyepieces. The price reduction includes TeleVue DIOPTRX™ Astigmatism Correction Lenses, Barlow lenses, Nagler eyepieces, Plossl eyepieces, Powermate lenses, and Radian eyepieces. For detailed price listings please read our TeleVue Product Prices page.

    • Updated Leica Prices page to reflect the latest increases necessitated by the devaluation of the US Dollar against the European currencies.

    Changes in September 2007:

    • Published our review of the new TeleVue 'Ethos' eyepiece. This new eyepiece design was previously announced at our TeleVue News & Developments page. But it was only in this month that we had the opportunity to experience it's 100 degree apparent field of view.

    • The introductory pricing and availability for the new TeleVue 'Ethos' eyepieces has been announced. This new eyepiece design was announced by TeleVue at an astronomy convention, while Company Seven was first to publicize it at our TeleVue News & Developments page. This stunning new eyepiece features a 100 degree apparent field of view. The Ethos series of eyepieces are coming available at Company Seven in September and since we have been accepting orders against our first shipment of 13mm Ethos, and now that we can actually say what these will cost we are proceeding to contacting those who are on our list to finalize the sales. The cost incidentally is somewhat less that we guess it would be, with an introductory price of $620. The cost is along the lines of the other TeleVue "Über Eyepieces" including the 31mm Nagler Type 5, nicknamed "The TermiNagler". Come visit one of the last remaining showroom oriented telescope specialty shops in the Americas to see the new 13mm Ethos.

    • Updated our Astro-Physics Product Availability Page to reflect the announcement of the new 140mm f7.5 Starfire EDF Apochromatic refracting telescope. These are available with the customer's choice of either 2.7 or 4 inch diameter focuser, and both of these are equipped with the popular FeatherTouch dual geared (1 to 1, and 9 to 1 reduction) focuser. The first production run is well underway, and we anticipate starting to make deliveries in September and October 2007! Company Seven will be referring to our waiting list to determine to whom our allocation will be offered, as such we will be selling these by invitation only.

    Changes in July 2007:

    • We started to accept new orders for the 2007 Model Astro-Physics 1200GTO German Equatorial Mounts on 12 July, anticipating delivery of the first mounts in the August through November 2007. Company Seven will refer first to our waiting lists of people who previously expressed their interest in these mounts, and we should have enough slots to accommodate all on our waiting list and some new comers too. You may refer to Astro-Physics 1200GTO and Astro-Physics GTO Control System pages for the most up to date information about these mounts.

    Changes in June 2007:

    • Added article "Arthur C. Clarke's comments about his Questar 3-1/2". An excerpt from the nonfiction book "The Treasure of the Great Barrier Reef" by Arthur C. Clarke (b. 1917) where he described his Questar 3-1/2 as "the finest small telescope ever built--the 3-1/2 inch Questar, a jewel of precision optics which has produced close-ups of the moon that could easily be mistaken for Mount Wilson photographs". We also add some notes that we found interesting about the the locations upon which the book is based. From Company Seven's archives.

    Changes in May 2007:

    • Updated our Geochron world time display section to show the various vinyl, wood, and leather finishes in which the Geochron can me made, and to clean up appearance and logical arrangement of the site. Also added articles to our Geochron Library describing how to install the Geochron with either the Surface Mount or Flush Mount hardware. The Geochron remains one of the most stunning and educational mechanical devices that can grace a home or office.

    • Updated our Universal Astronomics Price page to bring it in line with 2007 changes. This product line offers quite well engineered alt-azimuth mount systems for telescopes and wonderful parallelogram mounts for binoculars. But there are many choices with many names of products that are similar, so that it is daunting for the mere mortal to deconvolute the product descriptions and understand what really works with what. So we added illustrations to this page, and describe the items a bit better to help our own staff as well as our customers understand it better. In time we are likely to expand the UA area of our web site to include more of their interesting mount systems.

    • Added even more information about the new TeleVue 'Ethos' eyepieces at our TeleVue News & Developments page. This stunning new eyepiece features a 100 degree apparent field of view. The prototype 13mm model was announced to the public on 28 April and demonstrated on the TeleVue NP101 attaining immediate critical acclaim. The Ethos series of eyepieces are expected to start coming available at Company Seven late in the Summer of 2007 and we are already accepting orders against our first shipments.

    • Company Seven made the earthshaking decision to accept PayPal form of payment. We are traditionally excruciatingly cautious not only about what we offer to our clientele, but also about new business methods. And so our accepted forms of payment now include:

      Check
      Check or Money Order

      Mastercard

      Traveler Check

      PayPal
      VISA
      VISA

      Western Union

      Wire Transfer

      For additional information refer to our Ordering Information page. But our clients should not be too concerned about this trend at Company Seven to operate something like a business; we will retain our unique character.

    Changes in April 2007:

    • Added new illustrated article in our Questar Library section describing the Questar Declination Vernier Manual Drive which was made through the 1980's for the Questar Standard and Questar Duplex 3-1/2 telescopes. Unit illustrated is from Company Seven's Museum Collection. Also added to our Questar Library Questar Powerguide Drive & Corrector describing an original AC and 12 volt DC powered drive control system for the Questar Fork Mounts. The Powerguide shown here is also from Company Seven's Museum Collection. Our goals include to be able to host an on line virtual museum that shows items that we have on display in our showroom and archives.

    • Posted "Testing the Zenithstar 110 Triplet Apo" by Jan Adelaar and Fred Hissink of The Netherlands at our William Optics Notes & Interesting Articles page. This beautifully done complete five page color illustrated review of this versatile telescope. Includes sketches of Jupiter, reviews of deep sky obseving, discussion of experiences with imaging through the ZS 110 with a Digital SLR Camera accompanied by sample images of: The Great Nebula in Orion M-42, Saturn (with two of it's moons), and the Earth's Moon.

    • Added illustrated review about the newly introduced Orion 120mm ED a 4.72 inch aperture f/7.5 apochromatic refracting telescope. This optical tube assembly is even better suited for most astronomical applications than it's popular smaller cousins the Orion 100mm ED and 80mm ED which were both introduced with much critical acclaim.

    • Updated Technical Innovations Dome Prices page.

      Also added a new publication "Remote Control Astronomy Handbook" to our Technical Innovations Notes and Interesting Articles index page. Until now, there has been little printed information available on creating and operating robotic observatories with contemporary observing equipment and computers. This illustrated 57 page booklet as a service to the astronomy community by drawing on the experiences of the authors and that of our customers. This booklet will help you learn the practical side of operating a telescope and observatory by remote control. The Remote Control Astronomy Handbook describes how to automate an observatory including sections about the observatory, the telescope, cameras and computers. It is intended primarily for astronomers at the advanced amateur level and for professionals who need some orientation to the subject. Published March 2002 by John and Meg Menke, of Menke Scientific, Ltd. Copyright John & Meg Menke, from Company Seven's Library. Download size is 505,058 bytes (in Acrobat Reader ".pdf" format).

    • Updated Leica Prices page to reflect the 2007 pricing.

    • Updated Product Lines page to reflect the introduction of William Optics line of refracting telescopes and accessories. We have started to put this section on line and expect to get into publishing some detailed overviews of the individual telescopes that we are evaluating and showing including the Megrez 90 APO, FLT 110, and FLT 132 telescopes.

      As a side note, Company Seven's primary area of work is for Government and industry; the profits from this work have historically permitted our staff to operate the astronomical side of our business in a rather idealistic manner. However, recent demands upon our most capable staff, including extensive travel to overseas, have left us lacking the people to maintain and update this Web Site as we would routinely have preferred to do. Furthermore, we can not simply trust hiring a "Beltway Bandit" with no knowledge of our industry to maintain the site and provide the valuable and insightful content. So we ask for your patience as we adapt to the changing demands made of us. Note, our routine practices and our showroom operations continue unabated.

    Changes in September 2006:

    • Hosting an ilustrated article not related to Company Seven directly but interesting nonetheless since it explains what went wrong when one of our staff ordered a custom high tech bicycle frame based a well regarded manufacturer Internet advertising and catalogs, and those of the US based importer. My Colnago Misadventure: A C-50 FLR Bicycle Frame Nightmare, is an excellent business school lesson on how not to deliver what was promised, and then how to make attempt poor attempts to excuse even after the customer clearly shows what he received is not what was represented, and finally how to turn the customer completely off to your company. This is interesting, amusing, and almost tragic reading for any corporate CEO.

    Changes in June 2006:

    • Put on line an overview of the Questar 50th Anniversary Model, a limited production telescope that we have been offering since it was introduced in 2002. We are finally getting around to writing it up as we work to fill out our Questar section.

    Changes in May 2006:

    Changes in April 2006:

    • Put on line an overview of the new Vixen Skypod, a STAR BOOK TYPE S computer controlling a "Go To" alt-azimuth mount. The Vixen North America company is not importing this to the USA, not even offering it through their preferred three "E-Tailers". However, Company Seven will provide this product as a service for clients of Company Seven only on a special order basis. If demand accelerates then we may show the mount in our showroom. In time, we expect Vixen North America will offer and support the product too.

    • Put on line the page Company Seven ATA Cases for Telescopes, Mounts, Sensitive Instruments providing a brief overview of the custom designed transport and storage cases we make for optical and mechanical systems, for sensitive electronics including computer CPU's and monitors. Our ATA cases meet or exceed all the requirements set for the by the Airline Transport Association. Our Military Spec. cases add to the durability of the ATA cases added resistance to environmental extremes and anti reflection treatment of the hardware.

    • Expanded the page Company Seven Telescope & Lens Repair or Refurbishment Services to include illustrations of recent projects undertaken by Company Seven for one of our long term customers featuring "The Poster Child of Abused Telescopes".

    • Put on line the David H. Levy Guide to the Stars, our most recommended Planisphere. The night sky is mapped with the Constellations being those patterns recognizable to man since time immemorial. Constellations can be thought of as countries or states on a world map, where if you seek the Grand Canyon then you know to find Arizona. While in the night sky when one seeks the Great Nebula then one looks toward the Constellation Orion. The Planisphere is the simplest device with which to start ones' trek into the night sky.

      The Planisphere makes it very easy for one to find out what constellations and major deep sky objects are up overhead at any given time of the day or night. These are made in two sizes 11 or 16 inch diameter, available in either English or Spanish, and for use in either Northern or Southern Hemispheres. These are a two piece plastic disc assembly with a map of the entire night sky one the rear chart disc, and another overlay disc attached over the chart disc. The overlay has a transparent window with a surrounding mask to simulate the North, South, East and West horizons. The overlay is dialed to line up its local time indicator marks with the Month and Day printed around the edge of the chart disc, and so when properly set this will reveal what parts of the sky may be seen at any time of the year. We prefer the larger 16 inch model because the writing is larger and easer to read under red flashlight. The print is black lettering against a white background sky and is easy to read under red light.

    Changes in March 2006:

    • Continued adding to our Fujinon section. Added our illustrated review of the 7x 50 FMTRC-SX Marine Binocular being a top rated, best buy in its class. The 7x 50 FMTRC-SX is a compass equipped cousin of the famous 7x 50 FMT-SX Binocular. And also posted an accessory for the 7x 50 FMTRC-SX, the Binocular Compass Illuminator for marine and terrestrial applications. Company Seven continues to be the only retailer working so diligently to inform its clientele!

    • Published announcement about the sale of DayStar Filter Co. assets to ICSTARS, a partnership based in Missouri that will operate from now on as "DayStar Filters Limited Liability Corporation". A reassuring touch to this article is that it includes a recent photo taken in February 2006 of Del Woods who has been recuperating from a life threatening illness that had left him incapacitated since 9 May 2005!

    • Added information and a photo of Ken Graun, the author of The Next Step - Finding and Viewing Messier's Objects.

    • Put a new section online about the Baader Planetarium including a brief overview of the company. Throught March we are gradually adding our images and informational reviews about the Baader products particularly focusing on several their most highly regarded accessories and filters.

    Changes in February 2006:

    • Reviewed and profiled the Questar Photo-Visual Color Filter Set. This is a set of ten filters for photographic and visual uses in terrestrial as well as astronomical applications.

    • Reviewed and profiled the Vixen Porta Mount. This is a new compact, geared alt-azimuth mount with tripod set that is quite suitable for use with many compact telescopes for terrestrial uses (panoramic, birding, etc,), and visual astronomy.

    • Posted review of a book we are stocking, The Next Step - Finding and Viewing Messier's Objects by Ken Graun. A delightfully illustrated handy book with beautiful color pictures, color illustrations and charts, and with black and white photo plates of the Messier Objects. This book is an interesting read for those who appreciate the historical insights to the life of Charles Messier (b. 26 June 1730 in Lorraine France, d. 12 April 1817 in Paris), the French astronomer who gave us the Messier Objects catalog of celestial wonders.

    • Began to post a new section on our Web Site, the new Fujinon pages. This is a product line that we have stocked for years but had not felt all that inspired to publish given the market conditions. However, this site is for the benefit and amusement of Company Seven's clientele first and foremost, and we felt they deserved to know more about these fine 50 mm (the 7x 50 FMT-SX being a top rated, best buy in its class for example), 70 mm, up to giant 150 mm binoculars.

    • Reviewed the Universal Astronomics UniMount™ alt-azimuth parallelogram platform for use with most larger consumer binoculars including several of the Fujinon binoculars mentioned above.

    • Announced the new Lightbridge™ 12. A new series of Truss tube Dobson style reflecting telescopes available in 8, 10 and 12 inch apertures. It has been said by many in our hobby that regardless of bells and whistles "bigger is better" and in practice this is true - as long as you can take the telescope to where you want it, when you want it: this is where Lightbridge™ comes in.

    Changes in January 2006:

    • Announced the new Astro-Physics Mach1GTO German Equatorial Mount. We provide pictures with a preview of this coming product that is in the prototype stage of development, as such features and specifications are preliminary and subject to change. While we do not routinely publish products that we have not yet evaluated firsthand, Astro-Physics credibility is so good that Company Seven did not hesitate to post this preview.

    • Revised our page describing the Questar Birder spotting scope. We provide new color pictures with a more comprehensive review of this reference standard product. The Questar Birder is an ultra compact, high performance telescope evolved from the Questar Field Model. But the Birder is provided with features and accessories more in keeping with the needs of the birding community in mind.

      We expect to start accepting orders for the Mach1GTO later in 2006 anticipating delivery of the first mounts in the Fall of 2006 or early in 2007. Company Seven will refer first to our waiting lists of people who previously expressed their interest in the now discontinued Models 400 GTO and 600E GTO mounts, while you newcomers who want the Mach1GTO are to be generally added to that list in chronological order.

    • Updated Consigned/Used Astronomical And Terrestrial Telescopes And Mounts page. Also updated Rotating Display, Used or Consigned Accessories page.

    • Updated TeleVue 76 Apochromat Refractor page. Revised description and included images of TeleVue 76 Apo to reflect new 2 inch focuser provided with these telescopes since late in 2005.

    • Updated Leica Sporting Optics Prices page. Also updated several pages describing the Leica binoculars with improved images taken in our showroom, and provided updated information about new or discontinued products.

    Changes in December 2005:

    Changes in November 2005:

    • Added illustrated review describing the newly introduced Orion SkyView Pro™ 150mm Maksutov-Cassegrain Telescope. This is a new compact and rugged telescope that is better suited for astronomical applications than it's popular smaller cousin the Orion StarMax™ 127 Maksutov-Cassegrain Telescope which was introduced in 2001 with much critical acclaim. Also updated our Orion Library section to include new instruction manuals for the 150mm Mak and other articles of interest to Company Seven's Orion customers.

      Updated our Astro-Physics Library section to include instruction manuals for the new German Equatorial Mounts and accessories, Electronics Support Files, Technical Drawings, and other articles of interest to Company Seven's Astro-Physics customers.

    Changes in October 2005:

    Changes in August 2005:

    • Added information to the page describing the new Astro-Physics Starfire 160 EDF Air Spaced Triplet Apochromat Telescope. Our first instrument arrived for display on 11 August 2005 (just in time for Mars!). This is among the first production of a new Christen air spaced design introduced on 5 November 2004.

    • Added information about the new Astro-Physics 4mm Super Planetary Eyepiece to our overview of the series. Our first 4mm SPL arrived on 11 August 2005 and completes the set on display.

    Changes in July 2005:

    • Revised our page describing and illustrating the new redesigned TeleVue 2 inch Focuser as is now provided with the new 127 and NP101 Apo telescopes. The plan is to eventually provide all new TeleVue 76mm and 85mm telescopes sold at Company Seven with this model 2" focuser too.

    • Posted new pages reviewing and describing the Leica ULTRAVID 8x 20 and ULTRAVID 10x 25 BL and BR series compact binoculars. Available clad in rubber or in black leather, these are a handy and worthwhile product that are the first choice in their class of several employees of Company Seven and many of our most demanding customers.

    • Wrote articles describing a unique new product series by TeleVue Optics; the DIOPTIX™ Eyesight Astigmatism Correction Lens. DIOPTRX is a unique accessory series that installs onto the top of a number of compatible TeleVue eyepieces (listed below) to correct views from a telescope which have would otherwise be distorted or blurred by eyesight astigmatism. We also uploaded new articles to our TeleVue Library section:

        1. PDF IconDIOPTRX Technical Notes An illustrated two page overview of the DIOPTRX provided as an Adobe .pdf file, April 2005 by TeleVue Optics (328,734 bytes).

        2. "Report By Al" This is a brief description of this unique product by Al Nagler, followed by comments from the first amateur astronomers who were able to evaluate DIOPTRX. June 2005 by Al Nagler, TeleVue Optics.

        3. PDF IconUnderstanding Your Eyeglass Prescription for Astigmatism An one page informative article describing visual astigmatism, particularly helpful in understanding the DIOPTRX Lenses. Provided as an Adobe .pdf file, April 2005 by Barry Santini of TeleVue Optics (27,634 bytes).

    Changes in June 2005:

    • 21 June 2005 Event: Martin Cohen of Company Seven was an invited guest on the American University Public Radio station WAMU "Kojo Nnamdi Show". Martin was among a panel of three in a discussion with the program host about amateur astronomy technology on the WAMU American University Public Radio "Kojo Nnamdi Show" weekly "Tech Tuesday" program.

      As described by the AMU staff "technology is driving a revolution in amateur astronomy. Improvements in telescopes, computerized data, cameras, and more means backyard stargazers now have access to information that only a few years ago would have been limited to the hands of experts. A look at the technology of amateur astronomy -- and what you might discover by just looking up."

      To read an more in depth review of the program with links to the program Web Site and a link to download the program in Real Audio file format please click here.

    • Repaired and updated our pages which host a Clear Sky Clock and our page showing a partial selection of other Clocks For Sites Located Within Sixty (60) Miles Of Washington, D.C. . The Clear Sky Clock is an automatically updated Internet site which at a glance shows when it will be cloudy or clear for up to the next two days for more than two thousand locations now; when Company Seven first went on line with this there were about 70 locations!

      The Clear Sky Clock we feature shows a prediction of when the area around the University Of Maryland Observatory in Adelphi, Maryland will have good weather for astronomical observing. The Observatory is quite near to Company Seven in Laurel and so we employ this clock as a public service for our readers. We did not realize that the author's links had changed some time ago, and so we apologize to our readers for our oversight.

    Changes in May 2005:

    • Updated our article How to Clean Optics on $500 Or Less. This describes how to optical elements of most consumer telescopes, their mirrors, eyepieces, binoculars, etc. The techniques described apply to most consumer optics too. Rearranged the article to provide additional illustrations and teach a more orderly approach.

    • Put new article on line describing the "Astro Kit Camera Drive", a discontinued compact "poncet" style tracking platform sold during the 1980's. These were sold as tracking platform kits in the 1980's for wide sky astrophotography. The assembled unit illustrated in this article with its documentation are now in the collection of Company Seven.

    Changes in February 2005:

    • Working on complete revision of one of our older web site sections, first new item to go on line is the awesome JMI RB-10, a 10 inch Reverse Binocular Telescope. One of the first production RB-66, 6 inch Reverse Binoculars was introduced at Company Seven in the Spring of 2003. We have placed numerous images of prototype and production RB-10 and RB-66 models on line.

      And since the first several of the new RB-16 Reverse Binocular Telescopes sold are coming through Company Seven, this new 16 inch system is previewed on line with specifications and images from the prototype RB-16; this will be expanded soon after these first production models arrive.

    • Updated our article about How To Choose Your Questar 3-1/2 Telescope to provide additional details about mirror substrate choices.

    • Updated TeleVue 127 telescope page to reflect our experience with these telescopes since they were introduced at Company Seven in January 2003. Also added images of production models.

    • Updated Orion IntelliScope™ Computer Control page to reflect change to EPROM permitting longer observing time without having the power saver function cut off the unit. This is an available update to older IntelliScope™ Computer Controllers requiring return of the Keypad to Company Seven, and is standard on all new IntelliScope™ Computer Control keypads.

    • Added page describing and illustrating the TeleVue Equalizer bronze 2 to 1.25 inch reducer adapter.

    • Updated TeleVue section pages for future growth. Added page describing and illustrating the Air Chair pneumatic adjustable height observing chair.

    Changes in January 2005:

    • Posted our overview of the new Astro-Physics Starfire 160 EDF Air Spaced Triplet Apochromat Telescope, a new Christen air spaced design introduced on 5 November 2004. Also updated the section availability and product pricing pages. Company Seven is now accepting new orders for the new 160 EDF telescope, but we will be offering these by invitation only, referring to our waiting list of clients who have asked to be considered for the Starfire 155mm EDF first.

    • Updated Observing Tips for The Month page.

    • Daylight Savings to Standard Time switchover made for Home and Index pages. We are certainly paying more attention to the Geochron on display in our showroom as we close in on the coming Winter Solstice next month.

    Changes in October 2004:

    • Added new illustrated article The Vixen Sphinx Equatorial GoTo Mount. An overview of the the Sphinx SXW German Equatorial Mount system written by Mr. Ron Lee written in August 2004 for Company Seven. Copyright Mr. Lee, for Company Seven's Library.

    Changes in September 2004:

    Changes through August 2004:

    • Company Seven very rarely uses the term Sale because we do not believe think that alone should usually provoke people to buy. But here for the first time we announced an unprecedented TeleVue Optics Factory Authorized Sale which provides new customers starting out, and old with voids in their eyepiece collections with a great opportunity to own some magnificent eyepieces. This sale applies to many of the more advanced TeleVue eyepieces including all of the Nagler, Nagler Zoom, and Radian series eyepieces. And the sale includes their Bandmate Nebular Filters.

    • Posted article explaining and illustrating the new Astro-Physics Feather Touch® Micro Focuser. The first page describes the product, and how those whom already own an Astro-Physics telescope may be able to add this option. Also revised Traveler 4 inch Apo telescope page to incorporate new information and images about Feather Touch®, and our Universal Astronomics alt-az mounts. Prices have been posted on our Astro-Physics pricing page since these were announced in late 2003 but we waited to publish our appraisal of this new product until we could obtain production models which are now on display in our showroom.

    • Posted first installations of a new section of our Internet site describing the Vixen product line of telescopes, mounts, and accessories. We provide an overview of the company at our Vixen Index page, with a more detailed article about Vixen Co., Ltd. History on line too.

    • Posted an entire new section explaining and illustrating the NRD Staticmaster™ Alpha Ionizing Brushes. These remain the best portable solution for eliminating dust and static attraction on optical surfaces. These devices are also suitable for use with photographic films, for cleaning scanners, compact discs, slides, lenses, and filters. Prices have been posted on our pricing page.

    • Posted article explaining and illustrating the new Astro-Physics Super Planetary Eyepieces. Prices have been posted on our Astro-Physics pricing page since these were announced in February 2004 but we waited to publish our appraisal of this new design until we could obtain a production set. We will probably update this in time as we complete additional planned testing. We have placed a set of these on display in our showroom.

    • Posted new page describing and illustrating the highly regarded Baader Mark V Großfeld Binocular Head, a top of the line system providing high resolution binocular views through telescopes. This system was introduced in 2003 and we are just getting around to placing it on line - we were in no rush since the wait list runs from six months to a year or more!

    • Introduced the new Orion SkyView Pro™ 100mm ED at Company Seven's showroom on 6 August. A complete 4" f9 Apo telescope, this is the long anticipated larger cousin of the popular Orion 80mm ED 3.15" f7.5 ED Doublet Apo.

    • SPECIAL NOTES for December 2003

      1. Often the volume of incoming E-Mail that requires our writing a detailed technical reply precludes a more prompt reply to other E-Mails by Company Seven. We are happy to offer sound advice to those in need, and E-Mail can be good for this use especially for more distant customers. However, E-Mail is in some measure abused by some who have forgot how and when to use a telephone. Aside from the volume of inquiries, E-Mail is also subject to problems with some who accidentally provide an incorrect return E-Mail return address; there have been times when we send an E-Mail reply and it is returned or blocked by the customer's automated spam filter.

      Over recent years we have assigned additional resources to meet the high and increasing demands brought about by the Internet, and by increased word of mouth exposure. However, it is often impossible to reply to all inquiries, or to inquiries that we judge to be answered better with a simple phone call. So, when you do require a prompt reply to an urgent matter then please either telephone our showroom on 301-953-2000, or E-Mail and be patient. If no reply to your E-Mail arrives within a few days then you may send it again.

      2. On 16 December we completed hardware and software changes to our E-Mail system. So those E-Mail's that arrived between 7 December and 16 December were received, and stored, and we are gradually working through the backlog as well as new E-Mail inquiries. We apologize for the inconvenience or undue concern.

      3. The recent Mars Opposition and conservative planning by manufacturers has resulted in shortages of supply of several popular telescopes, especially those which are most popular among those entering the hobby. While the demand for new telescopes by customers contacting our Laurel, Maryland showroom has increased particularly dramatically over the past weeks. And so for new orders received after 1 December 2003 we are reserving inventories of several of the very popular instruments for pickup at our showroom only. We will continue to accept mail and phone orders for both delivery and local pickup, but those new orders placed on 1 December or later are not likely to be shipped out until after the Christmas rush, probably in January 2004 or possibly even later for some instruments. This will reduce the chances of our having to deal with shipping related losses in transit, and will make virtually every telescope we accept available for pickup in our showroom.

    • Updated Kendrick Pricing section, to reflect product line additions and deletions. Kendrick of Candada is most well known for their lines of telescope Heater and Dew/Frost Prevention systems, Dew Shields, Portable Rechargeable Battery packs, and Solar Filters.

    • Updated Leica News section to reflect new product announcements, review new binoculars, post new product prices, and product line additions and deletions. Most importantly, we began to put information on line about the new Leica ULTRAVID binocular series.

      Company Seven has been aware of this new product series since it was announced in August 2003, but we decided to wait until we could actually evaluate production models before we published our review. You may now read about the ULTRAVID 42 BR, ULTRAVID 42 BL, and ULTRAVID 50 BR models on line, and see these instruments in our showroom.

Programming that script was fun!

    • Added a new edition of a popular book on line. High on our suggested reading list is the "Observers Handbook 2004". Published by The Royal Astronomical Society of Canada, the "Observers Handbook" is one of Canada's oldest scientific publications continuously published since 1911 with origins to 1907. The "Observer's Guide" includes includes discussions and drawings of periodic astronomical events that are known to be coming in that year, as well as good coverage of topics and astronomical data. This is the 306 page annual paperback guide that is most highly recommended by Company Seven for the novice, or for the experienced observer.

    • Few Web Changes due to vacations. We belatedly updated Observing Tips for The Month page.

    Changes through August 2002:

    • Added interesting news article about a lawsuit filed against a major manufacturer of telescopes who are not represented by Company Seven - but we would post this either way. For years Company Seven has complained to several manufacturers, some of whom we represent, that their advertising, packaging and marketing materials are misleading. We have gone so far as to post warning about what we consider to be unfair or misleading telescope sales practices in our article "Advice for Beginners (or Anyone) Seeking to Buy A Telescope" in the "Promise Them Anything" portion of this article. On May 17, 2002, two individuals filed a complaint for unfair business practices in their capacity as consumers, within the meaning of the Consumer Legal Remedies Act, and in their capacity as private attorneys general suing to enforce the provisions of California Business and Professions Code Section 17200. The complaint which was filed in the Superior Court of California, County of Ventura (Case No. CIV211644) claims that certain of the company's packaging and marketing materials are misleading.

      It may just be the the defendant in this case happens to be the first to be confronted with a lawsuit for alleged practices on their part that in our experience have been for too long, wide spread in the amateur-oriented telescope market. Read more about this story.

    20 March 2011 Event: Company Seven Supporting NASA Sun-Earth Day Activities (19 March)
      SunEarth Day 2011 Logo (103,364 bytes)

      Sun-Earth Day is a national celebration of the Sun, the space around the Earth (geospace), and how all of it affects life on our planet. Over the past eleven years, NASA Sun-Earth Connection Education Forum has sponsored and coordinated education and public outreach events to highlight NASA Sun-Earth Connection research and discoveries and Company Seven has supported these events with complimentary events at our Maryland showroom or nearby. The strategy involves using celestial events, such as total solar eclipses and the Transit of Venus, as well as Sun-Earth Day during the March Equinox, to engage K-12 schools and the general public in space science activities, demonstrations, and interactions with space scientists.

      For Sun-Earth Day 2011 the theme is 'Ancient Mysteries-Future Discoveries', opening the door to a much deeper understanding of our Sun and its impact on our Earth across the ages. We will also consider how the Sun continues to impact our daily lives. For example, did you know that between May 10-12, 1999 the solar wind nearly vanished, causing Earth's magnetosphere to expand in volume by over 100 times!

      Live Webcast On March 20, 2011, join us for a live Sun-Earth Day Webcast. In partnership with NASA EDGE, the Sun-Earth Day team will produce video and webcast programming that will be shared with formal and informal education audiences worldwide. The programs will highlight several sites including: Chaco Canyon (New Mexico), Hovenweep (Utah), Chichen Itza (Mexico), Cahokia Mounds (Illinois), and Sunspot (New Mexico). Many of these sites present unique opportunities to develop authentic cultural connections to Native Americans, highlighting the importance of the Sun across the ages. We will involve scientists, their missions, and research programs to share NASA heliophysics research with diverse audiences.

      The award winning NASA EDGE team is known for their offbeat, funny and informative look behind the NASA curtain. Their guests include scientists, educators and students who will! If you've ever wanted to learn about NASA but thought you needed to be a rocket scientist, wait no longer!

      In coordination with NASA and fellow participants, Company Seven will celebrate Sun-Earth Day 2011 by providing educational literature to local schools upon request well in advance of 20 March. Since the Sun-Earth Day 2011 occurs on a Sunday when our showroom is routinely closed, on Saturday 19 March (weather permitting) we will take a journey to our Sun. Activities will feature Solar Observing, with several premium telescopes equipped to observe the Sun in "white light" or in "Hydrogen Alpha" and "Calcium K-Line" with DayStar and Lundt made filters. Visitors who wish to take home an image of the Sun will be helped to attach their compatible film or video cameras (we suggest calling us in advance) to our telescopes. News media who wish to obtain a video feed should contact us in advance too. at our Laurel, Maryland showroom/museum. These filters permit the safe observing of the Sun revealing Solar Prominences, Sunspots, Faculae, the Photosphere, and more.

      NASA's Office of Space Science (OSS) explores four broad themes: "Sun-Earth Connection," "Solar System Exploration," "Structure and Evolution of the Universe," and "Astronomical Search for Origins and Planetary Systems." For each of these themes OSS has created an "Education Forum" so that educators, students and the public can share the excitement of those discoveries and knowledge generated by Space Science missions and research programs. The Sun-Earth Connection Education Forum is a partnership between NASA/Goddard Space Flight Center and UC Berkeley's Space Sciences Laboratory whose mission is to increase science literacy and steward Sun-Earth Connection science resources.

      SunEarth Day 2006 Logo (45,218 bytes)
      Sun-Earth Day is comprised of a series of programs and events that occur throughout the year culminating with a celebration on or near the Spring Equinox. Over the past six years, the NASA's Sun-Earth Connection Education Forum has sponsored and coordinated education and public outreach events to highlight NASAs Sun-Earth Connection research and discoveries. The strategy involves using celestial events, such as total solar eclipses and the Transit of Venus, as well as Sun-Earth Day during the March Equinox, to engage K-12 schools and the general public in space science activities, demonstrations, and interactions with space scientists. This year's theme will be "Living In The Atmosphere of The Sun".

      SunEarth Day 2006 Logo (11,298 bytes) In collaboration with partners that include science centers and museums around the world, the Exploratorium, NASA Connect, Sun-Earth Connection missions, Company Seven and others, NASA produces webcasts, other multi-media, and print resources for use by school and informal educators nation-wide and internationally. The NASA Sun Earth Forum provides training and professional development to K-12 educators, museum personnel, amateur astronomers, Girl Scout leaders, etc., so they can implement their own outreach programs taking advantage of our resources. A coordinated approach promotes multiple programs occurring each year under a common theme. The Sun-Earth Day website contains information for students, educators, scientists, museums and amateur astronomers! All web resources for prior events such as "Sun-Earth Day 2005: Ancient Observatories, Timeless Knowledge" are archived and will remain on-line for your enjoyment!

      Right: NASA will provide LIVE WEBCAST COVERAGE of the Total Solar Eclipse from Turkey on 29 March 2006!

      In response to the annual request from NASA, Company Seven will continue to help celebrate Sun-Earth Day 2006 on March 20 with Solar Observing (weather permitting) and an Open House from 11 am into the afternoon, and on Saturday 24 March with Solar Observing (weather permitting) and an Open House at our Laurel, Maryland showroom/museum. Activities will include light fare and refreshments, and we will feature Solar Observing, with several premium apochromatic refracting telescopes equipped to observe the Sun in "white light", and in "Hydrogen Alpha" and "Calcium K-Line" with DayStar filters. Visitors who wish to take home an image of the Sun will be helped to attach their compatible film or video cameras (we suggest calling us in advance) to our telescopes. News media who wish to obtain a video feed should contact us in advance too.

      SunEarth Day 2005 Logo (67,207 bytes)
      Sun-Earth Day is comprised of a series of programs and events that occur throughout the year culminating with a celebration on or near the Spring Equinox which occurs this year on 20 March. Over the recent years, the NASA's Sun-Earth Connection Education Forum has sponsored and coordinated education and public outreach events to highlight NASAs Sun-Earth Connection research and discoveries. The strategy involves using celestial events, such as total solar eclipses and the Transit of Venus, as well as Sun-Earth Day during the March Equinox, to engage K-12 schools and the general public in space science activities, demonstrations, and interactions with space scientists. This year's theme will be "Ancient Observatories Timeless Knowledge".

      The Ancient Observatory theme for 2005 features solar alignments with structures that mark the equinoxes and/or solstices. In partnership with the Exploratorium, Ideum, and NASA Connect, NASA's Sun-Earth Connection Education Forum will produce video and webcast programming that will be shared with formal and informal education audiences nationally. The programs will feature several sites including: Chaco Canyon (New Mexico), Hovenweep (Utah), and Chichen Itza (Mexico). Many of these sites present unique opportunities to develop authentic cultural connections to Native Americans, highlighting the importance of the Sun across the ages. We will involve Sun-Earth Connection scientists, their missions, and research programs to share NASA solar research with diverse audiences.

      The goals of this event include that participants of our program will benefit from the following key understandings:

      • The Sun is a dynamic, magnetic star that impacts the Earth and other planets in our solar system
      • Understanding the mysteries of the Sun has been a primary motivator for Sun watchers over time
      • Human beings use technology (past, present, and future) to understand the Sun and the Universe beyond
      • Light has always provided a means of investigating the Universe
      • Human beings from diverse cultures have viewed the Sun as the source of life
      • Stewardship of these sacred sites is our collective responsibility

      In collaboration with partners that include science centers and museums around the world, the Exploratorium, NASA Connect, Sun-Earth Connection missions, Company Seven and others, NASA produces webcasts, other multi-media, and print resources for use by school and informal educators nation-wide and internationally. The NASA Sun Earth Forum provides training and professional development to K-12 educators, museum personnel, amateur astronomers, Girl Scout leaders, etc., so they can implement their own outreach programs taking advantage of our resources.

    20 March 2004 Event: Company Seven Supporting NASA Sun-Earth Day Activities

      SunEarth Day 2004 Logo (45,218 bytes)
      Sun-Earth Day is comprised of a series of programs and events that occur throughout the year culminating with a celebration on or near the Spring Equinox. Over the past six years, the NASA's Sun-Earth Connection Education Forum has sponsored and coordinated education and public outreach events to highlight NASAs Sun-Earth Connection research and discoveries. The strategy involves using celestial events, such as total solar eclipses and the Transit of Venus, as well as Sun-Earth Day during the March Equinox, to engage K-12 schools and the general public in space science activities, demonstrations, and interactions with space scientists.

      This year's theme will be "Venus Transit 2004". A transit of Venus across the disk of the Sun is among the rarest of planetary alignments. The last transit occurred 120 years ago in 1882, while the next one takes place on 2004 June 08. Opportunities are available to prepare for the viewing of the event. The NASA Sun-Earth website has been developed to provide the necessary resources and opportunities for participation in our fourth Sun-Earth Day. This year's program will continue to offer new and exciting space science content that will cross all of space sciences, offering activities and resources for every classroom and museums event. The goal is to involve as much of the student population and the public in this event as possible and to help them understand the immense importance and excitement surrounding this and previous transits. Through engaging activities focused on US and world history, music, technology, math, and astronomy, classrooms and museums can create their own event or participate in one of the opportunities we make available. Comparisons of Venus with Earth and Mars, calculations of the distances to nearby stars, and the use of transits to identify extra-solar planets will all add to the excitement of this cosmic occurrence.

      In response to the annual request from NASA, Company Seven will continue to help celebrate Sun-Earth Day 2004 on Saturday March 20 with Solar Observing (weather permitting) and an Open House from 11 am into the afternoon, and with Solar Observing (weather permitting) and an Open House at our Laurel, Maryland showroom/museum. We will host a similar opportunity to view the Venus Transit on the early morning of June 8. Activities will include light fare and refreshments, and we will feature Solar Observing, with several premium apochromatic refracting telescopes equipped to observe the Sun in "white light", and in "Hydrogen Alpha" and "Calcium K-Line" with DayStar filters. Visitors who wish to take home an image of the Sun will be helped to attach their compatible film or video cameras (we suggest calling us in advance) to our telescopes. News media who wish to obtain a video feed should contact us in advance too.

    20 March 2002 Event: Company Seven Supporting NASA Sun-Earth Day Activities

      SunEarth Day 2002 Logo (31,936 bytes)
      NASA's Office of Space Science (OSS) explores four broad themes: "Sun-Earth Connection," "Solar System Exploration," "Structure and Evolution of the Universe," and "Astronomical Search for Origins and Planetary Systems." For each of these themes OSS has created an "Education Forum" so that educators, students and the public can share the excitement of those discoveries and knowledge generated by Space Science missions and research programs. The Sun-Earth Connection Education Forum is a partnership between NASA/Goddard Space Flight Center and UC Berkeley's Space Sciences Laboratory whose mission is to increase science literacy and steward Sun-Earth Connection science resources. To visit the Web Site of the organizations involved, simply visit http://sunearth.gsfc.nasa.gov/SECEF_SunEarthDay/.

      Sun-Earth Day is a national celebration of the Sun, the space around the Earth (geospace), and how all of it affects life on our planet. In classrooms, museums, planetaria, and at NASA centers -- not to mention hundreds of National Astronomy Day celebrations -- the plan is to have a blast sharing stories, images, and activities related to the Sun-Earth connections in our solar system. Sun-Earth Day 2002 is sponsored by NASA's Sun-earth Connection Education Forum, the joint ESA-NASA Solar and Heliospheric Observatory mission, and The Astronomical League (sponsors of National Astronomy Day).

      In response to a request from NASA Goddard Space Flight Center, Company Seven will help to celebrate Sun-Earth Day 2002 on March 20 with Solar Observing (weather permitting) and an Open House from 11 am into the afternoon, and on Saturday 23 March with Solar Observing (weather permitting) and an Open House at our Laurel, Maryland showroom/museum. Activities will include light fare and refreshments, and we will feature Solar Observing, with several premium apochromatic refracting telescopes equipped to observe the Sun in "white light", and in "Hydrogen Alpha" and "Calcium K-Line" with DayStar filters.

      Reaching yet another stage in the public service oriented programs sponsored, supported, or operated by Company Seven, we have received a new DayStar 2.0 Angstrom Single Cavity Calcium K-Line University Series Filter for Solar Observing! This filter permits observation of the Sun's chromospheric network, a web-like pattern most easily seen in the emissions of the red line at 6563 Angstrom of hydrogen (H-alpha) and the ultraviolet line at 3934 Angstrom of calcium (Ca II K - calcium atoms with one electron removed). The network outlines the supergranule cells and is due to the presence of bundles of magnetic field lines that are concentrated there by the fluid motions in the supergranules.

      This new filter compliments the 0.5 Angstrom bandpass DayStar Hydrogen Alpha filter which we already own for observing the Sun's Filaments and Plage, Spicules, and erupting Prominences. Company Seven also maintains numerous white light filters to observe the Photospheric sunspots, bright Faculae, and granules to pretty well round out Company Seven's "Solar Observing Program" hardware.

      Aperture Stops are now in fabrication so that Company Seven will soon be able to operate the new Calcium K-Line filter on our Astro-Physics 155mm f7 EDF Apochromatic Refractor, while the Hydrogen Alpha filters will continue service on our Astro-Physics 130mm f8 EDT Apochromatic Refractor.

      Company Seven continues to sell and deliver the internationally acclaimed DayStar filters (now entering their 27th year!) to amateurs and to observatories and research organizations. To see amazing images and movies provided by these filters simply visit almost any major solar research facility web site, including that of the "Big Bear Solar Observatory" web site at "http://www.bbso.njit.edu" or any number of NASA or university astronomy sites.

      While the new arrival has already been greeted by comments from excited fans including "Awesome!", we also heard one "I must say, I am thoroughly impressed! I don't understand it, but I am, nonetheless, impressed!" To gain a better understanding of how significant this long awaited filter is, one should simply look at the faces of those across the river as Martin Cohen tells them "yes Virginia, there really is a Calcium K-Line filter".
