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.

The bright galaxies, star clusters, and nebulae catalogued in the late 1700s by the famous comet hunter Charles Messier are still the most widely observed celestial wonders in the sky. The second edition of Stephen James O'Meara's acclaimed observing guide to the Messier Objects features improved star charts for helping you find the objects, a much more robust telling of the history behind their discovery - including a glimpse into Messier's fascinating life - and updated astrophysical facts to put it all into context. These additions, along with new photos taken with the most advanced amateur telescopes, bring O'Meara's first edition more than a decade into the twenty-first century. Expand your universe and test your viewing skills with this truly modern Messier guide. It is a must for all budding night watchers.

Informal, story-telling approach Star charts, photos, and illustrations Interesting anecdotes, mythologies, and histories about the stars and constellations Brightest and best stars, star clusters and asterisms, nebulae, galaxies, variable stars and more Month by month, star by star, object by object, Stephen James O Meara takes readers on a celestial journey to many of the most prominent stars and constellations visible from mid-northern latitudes. Filled with interesting anecdotes about the stars and constellations and their intriguing histories, this book is both a useful guide for amateur astronomers, and a great first-time reference for those just starting out. After describing a constellation s mythology, readers are guided in locating and identifying its brightest stars in the sky, as well as any other bright targets of interest - colorful stars, double or multiple stars, star clusters and asterisms, nebulae, galaxies, variable stars, and more. This book will help beginning stargazers become familiar with the stars and constellations visible from their backyards, and explore the brightest and best stars, nebulae, and clusters visible through inexpensive, handheld binoculars.

Mars is a small world with a big reputation. This mysterious planet - with volcanoes that dwarf Mount Everest, a canyon system that would stretch fully across the USA and curious landscapes that may support life - has fascinated us for centuries. In the most up-to-date account available of the elusive `Red Planet', Stephen James O'Meara follows our longstanding love affair with this bewildering world, from the musings of humanity's first stargazers, to the imaginings of science-fiction writers and film-makers, to the latest images and discoveries from orbiting spacecraft and robotic rovers. The book also reviews plans for piloted missions to Mars, and what it will take for those missions to succeed.
