Guy Ottewell's Astronomical Calendar 2011
This famous atlas-sized annual book is the most widely used and most attractive guide to what will happen in the night sky throughout the year.
The Astronomical Calendar has been published continuously since 1974, and is used by more than 20,000 astronomers in over 100 countries.
An introduction explains how to use the various components of the book and, if you are a beginner, what to select at first. For each month there is a large map of the evening sky; facing it, a diary of 40 or so events, many with paragraph-long descriptions. Other features on the monthly pages include diagrams of where the planets are in their orbits, "Constellation Clues", "Telescopic Tour", "Observer's Highlights" and sketches of the most striking sky scenes. It is the one essential tool for every astronomer.
