Messier Objects

Charles Messier (1730–1817) was a French astronomer best known for his “Catalog of Nebulae and Star Clusters.” An avid comet-hunter, Messier compiled a catalog of deep-sky objects in order to help prevent other comet enthusiasts from wasting their time studying objects that were not comets.
