The New General Catalogue (NGC) is the most well-known catalogue of deep sky objects in amateur astronomy. It contains nearly 8,000 objects, known as the NGC objects. The NGC is one of the largest comprehensive catalogues, as it includes all types of deep sky objects (not specialised to just galaxies for instance).
The catalogue was compiled in the 1880s by J. L. E. Dreyer using observations mostly from William Herschel, and then subsequently expanded with two Index Catalogues (IC I & IC II), adding nearly 5,000 objects.
Objects in the southern sky are somewhat less well catalogued but many were observed by John Herschel. The NGC contained many errors which have for the most part been eliminated by the Revised NGC.
