QUESTAR REPAIR AND SERVICE, UPGRADES OR CONVERSIONSOnce In A Lifetime Telescopes: Questar is the longest-lived manufacturer making telescopes for the amateur market. However, what is even more stunning is that we still offer parts, service support and even upgrades for any Questar made since 1954! That is a fact that is even more amazing in the face of todays realities where many other makers today offer no repair parts or service support at all for telescopes that are not presently in production - hardly any others support a telescope that is decades old. So,
but also they who recognize these telescopes, while not inexpensive to acquire, offer the best long-term value.
Questar is the telescope for people who wish to buy such an instrument only once in their lifetime.
Company Seven Astro-Optics Division is the authorized agent for the Questar Corporation and as such we do offer full sales and factory warranted service support of all consumer and industrial products. All repairs are documented and entered onto the production and maintenance records of the particular instrument.

We strive to be informative and so we have listed prices for services and parts here that are current as of the time this article was authored. These prices are not likely to change over the course of a year or so and therefore these are good guidelines. However, you may wish to contact us for exact current prices.
Company Seven can not provide any information about how to disassemble our telescopes, nor can we sell any replacement parts which require disassembly of the instrument, or special installation procedures. We do however, post information at our our "Library" section explaining how to perform simple cleaning of the telescope exterior optics, and we can provide replacement attachments (Lens Cover, etc.).
Standard Service: In addition we do offer repair and maintenance services which are recommended for the Questar telescopes and microscopes periodically (depending on environment and uses of the instrument). For example, our Questar "Standard Service" program for conventional fork mounted telescopes includes:
Appraisals: If you plan to donate a telescope and will require a certified appraisal, then Company Seven can provide that professional appraisal of an instrument. The appraisal will be acceptable by the U.S. Internal Revenue Service, and most insurance companies. The cost of these services start at $100. It will require that the instrument be sent in to us or we visit for inspection.
Replacement Parts: If one is absolutely certain of what other repairs or service are necessary, then we can offer a more detailed reply about the cost of replacement parts. It is very likely that any external missing parts can be easily replaced, and service needs even of older instruments remain supported.
Any parts which we employ will be new, Questar replacement parts as installed on production telescopes. At times, older Questar telescopes (typically made before 1970) may require that we custom manufacture an exact duplicate replacement part. Or, we may be able to offer an identical used part that has been reconditioned to function and appear as new. Company Seven will never offer a used part unless we have the customers approval first; all normal guarantees apply.
Some of the commonly desired replacement or upgrade parts include:
If the telescope main optical system or its other components or oculars show a light haze then this may be fungal in origin. Superficial contamination by mold or mildew may usually be cleaned and the spores neutralized with modest expense of time and materials. Typically these organisms secrete enzymes that degrade materials into simpler substances which can be absorbed by the organism. These enzymes can not only dissolve the antireflective and protective coatings but given time will etch into the silica (glass) of the telescope. In these instances it is very important that the telescope be serviced as soon as possible, and before permanent damage occurs. If the glass is etched then it is usually not cost effective to grind, polish and figure the optics, so we would simply replace the optic(s) component after re matching or as a complete matched set (corrector lens and primary mirror) from a new production lot.
In any case we really need to inspect the optical tube to determine what repairs if any are needed. When a telescope is in such a poor condition that it is beyond being cost effective to repair, then we can accept them traded in against another instrument, or purchased outright where we will then either use them for parts or for static display in our telescope museum. Especially over recent years we see more and more used Questars being traded, some even misappropriated - 'eBay' bargains coming in for service where the unwary buyer thought he was getting a bargain, only to be shocked by the costs to refurbish the telescope.
To Return an Instrument: to us we suggest the telescope and any other optical accessories such as eyepieces be securely packaged. A local shipping/packing service may be engaged to do this. The instrument should be wrapped in bubble wrap, or if shipped in the original carrying case all voids within the case should be filled (between the fork arms and the walls of the carrying case, the void between the instrument lens cover and ceiling of the carrying case, etc,) with bubble wrap packing materials. Any loose items (eyepieces, etc.) should be bubble wrapped and packed with the case but not inside where they may work loose and scratch the telescope.
Be certain to enclose a letter with your name, shipping address, telephone number (day/evening), and E-Mail address describing what you wish to have done to the instrument. If paying by credit card then you may also include the card number and expiration date. The entire box should then be placed within a larger box with all voids within filled with packing materials.
Ship the package by either United Parcel Service Ground delivery, or UPS or Federal Express two or three day air, or by US Mail Priority service. A full value insurance for replacement of the contents should help to guarantee proper handling.
Any Questar instrument in need of service, conversion, or repair should be sent by carrier, or delivered in person to us insured through our showroom:
14300 Cherry Lane Court
Attn: Service Dept., Suite #117
Laurel, MD 20707
Please refer to the "Directions to Our Showroom" page at this site for directions with maps to visit our showroom
The turnaround time for either service or conversions will be about three to eight weeks depending on the nature of the work, and our current workload. The busiest time for us typically is between October and January, and so during these months service repairs may be delayed by up to an additional several weeks.
If we can be of assistance to you in any way, then please visit, or call us at 301-953-2000, or send E-Mail to Company Seven. Company Seven's highly expert staff will be your counsel to assist you to tailor an instrument to meet your personal goals, or the mission of your agency.
