1 Messier objects

Over the years, many astronomers have compiled catalogues of astronomical objects. One of the most well-known of these is the catalogue of Messier objects. This is a list of 110 objects visible from the Northern hemisphere using a small telescope, compiled between 1758 and 1782 by French comet-hunter Charles Messier.
