For more than two centuries, amateur astronomers have earned their stripes by observing the 109 star clusters, nebulae, and galaxies cataloged by French comet hunter Charles Messier. Now a new list of 109 equally appealing deep-sky delights is bringing a new generation of astronomers even closer to the beauty and mystery of the night sky. Carefully compiled by Sir Patrick Moore, the Caldwell Catalog covers the entire celestial sphere, highlighting cosmic wonders for observers worldwide. Stephen James O'Meara has tirelessly observed all 109 Caldwell objects. Deep-Sky Companions: The Caldwell Objects presents not only his beautiful sketches and detailed visual descriptions - it discusses each object's rich history and astrophysical significance. The latest fundamental data on each object are tabulated, and the book's star charts will lead observers to each object's precise location. This book is co-published with Sky Publishing Corporation.
