The Royal Astronomical Society of Canada "OBSERVERS HANDBOOK 2001"

Above: RASC "Observers Handbook 2001". Cover photograph of the Pleiades star cluster, one of the most popular astronomical objects. Three separate exposures were taken using a Pentax 6x7 cm format; two on black and white film and one on color, all of which were then digitally combined. Photo taken by the Editor, Rajiv Gupta using Astro-Physics 130mm f6 EDF Apochromat refracting telescope.

The "Observers Handbook" is one of Canada's oldest scientific publications. This is the 288 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.

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 takes the helm into the new millenium from Dr. Roy L. Bishop.

Considering it's content, while remaining only 5-1/2 inch wide, 8-1/2 inch tall, and 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:
