If there were a canon for viewing the night sky, Charles Messier would be its author. The galaxies, star clusters, and nebulae cataloged by the famous comet hunter in the late 1700s are still the most widely observed celestial wonders in the heavens. They are the favorite targets of amateur astronomers, with such rich variety and detail that they never cease to fascinate. This book provides new and experienced observers with a fresh perspective on the Messier objects. Stephen James O'Meara has prepared a visual feast for the observer. Using the finest optical telescopes available for amateur work, he describes and sketches the view from the telescope as never before. There are new drawings, improved finder charts, and new astronomical data on each object, including findings from the Hubble Space Telescope. Expand your universe and test your viewing acumen with this truly modern Messier Guide. It is a must for budding night watchers. Stephen James O'Meara is a contributing editor to Sky and Telescope.
