Messier Objects
The Messier objects are a group of deep sky objects catalogued by the French astronomer Charles Messier in the late 18th century.
Messier’s Catalogue des Nébuleuses et des Amas d’Étoiles (Catalogue of Nebulae and Star Clusters) is a collection of deep sky objects (galaxies, nebulae, star clusters) and other astronomical objects (asterisms, binary stars) that were visible with binoculars and telescopes at the time.
Messier compiled the list between 1758 and 1782.
