The Royal Astronomical Society of Canada "OBSERVERS HANDBOOK 2003"

cover of Observers Handbook 2003 issue
Above: RASC "Observers Handbook 2003". Cover photograph is an unusual image of a Leonid fireball. Meteor watching is among the most popular pastimes of serious observers or the beginner; the price of admission is free, and it is best accomplished by viewing with the naked eye from remote, dark sky location.

In 2001, the Leonid shower provided a spectacular display, with hourly rates for North American observers approaching or exceeding 1000 on the night of 17 November. Remarkably, the fireball in the photo happened to lie behind a stray cloud which was illuminated by the fireball as it passed under Saturn and toward the star Aldebaron. One exposure was taken using a 35mm camera with 35mm f/2 wide angle lens. The Fuji Superia 400 color film was exposed for 6 minutes. Tracking was accomplished using a home made "barn door" style mount. Photo taken by Barry Burgess, in St. Croix, Nova Scotia. click on the image above to view full size cover image

The "Observers Handbook" is one of Canada's oldest scientific publications. This is the 304 page annual guide that is most highly recommended by Company Seven for the novice, or for the experienced observer. This is a very readable, annual publication where the next edition becomes available in late October of each prior year for sale at Company Seven's Laurel, MD showroom. We will also deliver this by mail order to around the world.

This book helps one to plan an observing or astrophotography session well in advance of the date of the event. This book is a valuable resource with tables, formulae, and numerous articles of advice about astronomical objects, optics, human vision. In one simple to use reference you can find out: how many moons does Jupiter have? (and read information about each). How big is the Sun? When will an object be in a good part of the sky to view or image? How to observe? And much more. This is an excellent compliment to an optional star chart, and telescope/observing reference guide book such as "Starware" or "Backyard Astronomer's Guide".

Published annually since 1907 when it first appeared as "The Canadian Astronomical Handbook for 1907", it was created by C.A. Chant (b. 1865, d. 1956), Professor of Astronomy at the University of Toronto. His vision was of "a companion which the observer would wish to have in his pocket or on the table before him". It has been published as "Observers Handbook" since 1911, this has grown to be the most comprehensive yet lightweight and compact publication of it's type with Chant remaining as the Editor until the 1957 edition. The present (and 5th) Editor is Rajiv Gupta who took the helm into the new millennium from Dr. Roy L. Bishop.

Considering it's content, while remaining only 5-1/2 inch wide, 8-1/2 inch tall, and about 1/2 inch thick, this is a remarkably handy and easy to travel with publication. With contributing authors of the various sections being experts in their respective field. 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 including:
