New General Catalogue

The New General Catalogue (NGC) is the most well-known catalogue of deep sky objects (DSOs) in amateur astronomy. Containing nearly 8,000 objects it is one of the largest comprehensive catalogues ie. of all types of DSOs, not specialised to just galaxies for instance.

The NGC was compiled in the 1880s by Dreyer[?] using observations mostly from William Herschel, and then subsequently expanded with two Index Catalogues (ICs). Objects in the southern sky are somewhat less well catalogued but many were observed by John Herschel. Together with nearly 5,000 objects in the two ICs, the NGC naturally contained many errors which have for the most part been eliminated by the Revised NGC[?].
