The Royal Astronomical Society of Canada "OBSERVERS HANDBOOK 2006"

The team at Company Seven is very sorry to discontinue sales of this publication. Our shop can not buy in the quantities needed to obtain the better discounted pricing. As a result many astronomy clubs and other organizations buy and sell these books for less than what we pay. This ends a decades long tradition at C7, but we hope others will promote these good books as well as we used to.

Above: RASC "Observers Handbook 2006". Cover photograph shows the Horsehead Nebula. The back cover (not shown here) shows the Prancing Horse. Both celestial objects can be challenging visual observations, especially the former. Information about the Horsehead can be found on pages 60, 270, 278, and 282 of this Handbook issue. Page 282 also mentions the Prancing Horse.

The photo of the Horsehead Nebula was taken by Albert Saikaley of Ottowa, Canda who formed the composite image using a total of 106 minutes of exposure on a CCD camera using a 80mm (3.1 inch) aperture refracting telescope. Well-known Canadian astroimager Jack Newton produced the back cover photo, again a composit, from 20 minutes of exposures through a digital Single Lens Reflex (SLR) camera with 28 mm wide angle lens. Full frame versions of both images appear in the 2006 edition of the "RASC Observer's Calendar" sold at Company Seven.

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.
