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.
