The Caldwell Catalogue, compiled by the late Sir Patrick Moore (1923-2012), has delighted amateur astronomers worldwide since its publication in 1995. Twenty years on, Stephen James O'Meara revisits his guide to these 109 deep-sky delights, breathing new life into them and the 20 additional observing targets included as an appendix. This second edition retains O'Meara's detailed visual descriptions and sketches, accompanied by stunning new images taken by amateur photographer Mario Motta and observations by Magda Streicher. The astrophysical descriptions have been updated to account for the many advances in our understanding of the objects, not least due to an armada of space-borne observatories and the new technologies used in large ground-based telescopes. Ideal for observers who have completed the Messier objects and are looking for their next challenge, Deep-Sky Companions: The Caldwell Objects is a fitting tribute from a renowned visual observer to one of astronomy's most famous personalities.

About the Author
O'Meara, Stephen James: - A superb writer, photographer, and naturalist, Stephen James O'Meara is author of several highly acclaimed books, including others in the celebrated Deep-Sky Companions series. O'Meara earned a Bachelor of Science degree from Northeastern University and is well known among the astronomical community for his engaging and informative writing style and his remarkable skills as a visual observer. O'Meara spent much of his early career on the editorial staff of Sky and Telescope before joining Astronomy magazine as its Secret Sky columnist and a contributing editor. Among his many achievements, he was the first to sight Halley's Comet on its 1985 return and the first person to determine the rotation period of the distant planet Uranus. One of his most distinguished feats was the visual detection of the mysterious spokes in Saturn's B-ring before spacecraft imaged them. O'Meara has been honored with several awards, including the prestigious Lone Star Gazer Award for 'advancing astronomy through observation, writing, and promotion, and for sharing his love of the sky', and the Caroline Herschel Award for his planetary discoveries. The International Astronomical Union renamed asteroid 3637 O'Meara in his honor. O'Meara is also a contract photographer/videographer for National Geographic Creative.
