Product Description
The book includes twelve all-sky star maps, one for each month of the year. Each of the 60 reprinted columns covers a small region of the sky visible in a particular month (a constellation or group of constellations, or even just a portion of a single constellation). It includes descriptions of the variable and multiple stars, star clusters, nebulas, and galaxies visible in that particular region of the sky. Each column has a clear and informative finder chart of the region being discussed to help you locate the objects by star-hopping. There's also a tabular listing of the objects being discussed, with basic information and their right ascension and declination coordinates for those who want to find them using setting circles or a scope's computer. Each column includes some of the basic science behind many of these objects, plus photographs of the objects by amateur astronomers, many using only 8" scopes. There are also challenge objects listed to encourage observers to test the performance limits of their equipment and improve their observing skills. The softbound book has 174 oversized 8-3/8" x 10-7/8" pages and enough observing challenges to keep every observer happy for a long, long time.
