Yes, Charles Messier was primarily known for his work with nebulae. He was a French astronomer who discovered a number of comets, but is best known for his catalogue of nebulae and star clusters. The Messier Catalogue contains 110 objects, including the Orion Nebula and the Andromeda Galaxy. Messier's work was instrumental in the development of astronomy, and his catalogue is still used by astronomers today.
