Charles Messier. The first edition of 1774 covered 45 objects (M1 to M45).The total list published by Messier in 1781 contained 103 objects, but the list was expanded through successive additions by other astronomers, motivated by notes in Messier's and Méchain's texts indicating that at least one of them knew of the additional objects.

Charles Messier (French: [ʃaʁl me.sje]; 26 June 1730 – 12 April 1817) was a French astronomer. He published an astronomical catalogue consisting of 110 nebulae and star clusters , which came to be known as the Messier objects , referred to with the letter M and their number between 1 and 110.
The main mirror was ground at the observatory by a home-made mirror grinding machine over a period of four years, however this piece of glass was damaged when sent away for aluminising. After a period of fundraising a mirror was purchased and installed in the telescope with Messier 42, the Orion Nebula, being the target for first light.
Messier 4 or M4 (also known as NGC 6121 or the Spider Globular Cluster) is a globular cluster in the constellation of Scorpius.
