Astronomical catalogues such as those for asteroids may be compiled from multiple sources, but most modern catalogues are the result of a particular astronomical survey of some kind. Since the late 20th century, catalogues are increasingly often compiled by computers from an automated survey, and published as computer files rather than on paper.
Tycho Brahe completed his catalogue with the positions and magnitudes of 1004 fixed stars in 1598. It was the major achievement in astronomy since the days of Ptolemy. Brahe's astrometric observations greatly improved on the positional accuracy achieved by his predecessors.[6][7]
The Messier catalogue: the Messier objects are a set of astronomical objects first listed by French astronomer Charles Messier in 1771. Nebulae and Star Clusters was published in 1781, with objects M1–M110.
The New General Catalogue or NGC, compiled in the 1880s by J. L. E. Dreyer, lists objects NGC 0001 – NGC 7840. It is one of the largest historical comprehensive catalogues, as it includes all types of non-stellar deep space objects.
Henry Draper's Henry Draper Catalogue, published between 1918 and 1924, lists more than 225,000 of the brightest stars, named using HD followed by a 6-digit number.
Sir Patrick Moore compiled the Caldwell catalogue in 1995 for amateur astronomers, as a complement to the Messier catalogue. It lists 109 bright star clusters, nebulae, and galaxies, named C1 to C109,[8] and is a list of deep-sky objects of interest rather than a catalogue in the professional science sense.[clarification needed] Other deep-sky observing lists for amateur astronomers predated it.
