This famous atlas-sized and richly illustrated book is the most widely used and most attractive guide to what will happen in the night sky throughout the year. Each page is the size of three or four of an ordinary book, allowing large spreads of mixed diagrams and text. The Astronomical Calendar has been published continuously since 1974, and is used by about 20,000 (amateurs, telescope-owners, clubs, teachers, planetariums, libraries, enjoyers of the sky) in over 100 countries.
