Messier Catalog

Charles Messier, French Astronomer 1730-1817. Messier compiled the famous Messier catalog, a list containing 110 celestial objects, including nebulae, clusters, and galaxies.
Charles Messier

Charles Messier was an astronomer who lived from 1730 to 1817. His dedication was discovering and observing comets, and he found indeed 13 and succeeded in 7 more independent co-discoveries. Because he did not at all care about other objects in the sky, he compiled a list that would help him not to run in these objects again. This list is known as the Messier catalog. It contains 110 objects, including nebulae, clusters and galaxies. The list is still very popular today with amateur astronomers, because the beautiful objects are relatively easy to find. This makes them great targets for both, observation and imaging.
