Messier List

The first Messier list of 45 objects was published in 1774 by the French astronomer Charles Messier, although a preliminary version had first appeared in 1771 and the last item was added in 1966 by Kenneth Glyn Jones, based on Messier's observations.

The list now contains 110 astronomical objects:
