The Messier catalogue is one of the most famous lists of astronomical objects, and many objects on the list are still referenced by their Messier numbers. [1] The catalogue includes most of the astronomical deep-sky objects that can be easily observed from Earth's Northern Hemisphere ; many Messier objects are popular targets for amateur ...

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.
Articles with the Messier number in the title use [[Category:Messier objects|###]], dropping the M prefix, and using only the number. The number should be padded up to 3 digits using zeroes. Articles without the Messier number in the title use [[Category:Messier objects]]. A redirect containing the Messier number should also be added to the ...
Messier 107 or M107, also known as NGC 6171 or the Crucifix Cluster, is a very loose globular cluster in a very mildly southern part of the sky close to the equator in Ophiuchus, and is the last such object in the Messier Catalogue.
Charles Messier added it to his catalogue of nebulous objects (now known as the Messier Catalogue) in March 1781. [8] It is one of the closest and brightest barred spiral galaxies in the sky, and is visible with binoculars. [9] It has an isophotal diameter at about 36.24 kiloparsecs (118,000 light-years).
[1] [4] Entries in the catalogue are designated with a "C" and the catalogue number (1 to 109). Unlike objects in the Messier catalogue, which are listed roughly in the order of discovery by Messier and his colleagues, [5] the Caldwell catalogue is ordered by declination, with C1 being the most northerly and C109 being the most southerly, [1 ...
However, Messier did not include the coordinates of M102 on his catalogue, leading to confusion about the exact object they observed. His description of the object was the following: Nébuleuse entre les étoiles Omicron du Bouvier & Iota du Dragon: elle est très-foible; près d'elle est une étoile de la sixième grandeur.
