Messier Catalogue

A catalogue of star clusters, nebulae and galaxies originally published by Charles Messier in 1774. Although not particularly extensive (there are 110 Messier objects, as compared with 7,840 in the New General Catalogue) the Messier catalogue numbers (such as M1 for the Crab Nebula, or M42 for the Orion Nebula) are still in wide use.
