[9] The catalogue consists of a diverse range of astronomical objects, from star clusters and nebulae to ...

The Messier catalogue was compiled by French astronomer Charles Messier during the late 18th century and consists of 110 relatively bright deep-sky objects ( galaxies , nebulae , and star clusters ).
