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. Sir Patrick Moore has compiled a new list of 109 deep-sky delights, the Caldwell Catalog, which covers the entire celestial sphere. Stephen James O'Meara has observed all 109 Caldwell objects and Deep Sky Companions presents his beautiful sketches and detailed visual descriptions and 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. Stephen James O'Meara is known worldwide for his precise drawings of astronomical objects as seen through the telescope. Among his many astronomical achievements, he was the first to sight Halley's Comet on its 1985 return; he noticed the dark spokes in Saturn's B ring before the Voyager 1 spacecraft imaged them; and he was the first person to determine the rotation period of the distant planet Uranus. The International Astronomical Union named asteroid 3637 O'Meara in his honor. He is also the author of Deep Sky Companions: The Messier Objects (Cambridge, 1998) and co-author with his wife, Donna Donovan O'Meara, of Volcanoes: Passion and Fury (Sky Publishing, 1994).

"...a great read" Bob Casgrain, Stardust

"The production values of the book are superb...The Caldwell Objects is strongly recommended to collections with an emphasis on amateur astronomy, and would certainly be appropriate for academic collections supporting astronomy programs that offer courses in deep sky observation." E-STREAMS

"After his brilliant Deep-Sky Companions: The Messier Objects, Steve O'Meara has done it again. Deep-Sky Companions: The Caldwell Objects is a beautifully written, personal guide for observing 109 of the most beautiful objects in the night sky, plus 20 more personally chosen deep-sky treasures. Coupled with O'Meara's own meticulous observations, the rich observational history and current scientific knowledge of each object bring this book to life, and the depth of O'Meara's writing makes it a real gem." David H. Levy, Parade Science Editor and Codiscoverer of Comet Shoemaker-Levy 9

"Stephen O'Neara's Deep-Sky Companions: The Caldwell Objects is an indispensable guide for anyone who observes the night sky with a quality amateur telescope from a reasonably dark place. Here are tips for viewing - and understanding! - more than one hundred entrancing galaxies, star clusters and nebulae available to the backyard enthusiast. With its wealth of scientific and historical information, and its poetic sensibility, the book gave me immense pleasure even before I left my easy chair." Chet Raymo, Author, 365 Starry Nights and an Intimate Look at the Night Sky

"I think this series will long survive as a great set of observing books." Planetarian, Karl von Ahnen, De Anza College
