New General Catalogue
The New General Catalogue of Nebulae and Clusters of Stars, which is abbreviated as NGC was originally compiled by John Dreyer in 1888, containing nearly 8,000 objects. It was later extended by the Index Catalogue, adding 5,000 more entries.
NGC was originally published on Memoirs of the Royal Astronomical Society as "A New General Catalogue of Nebulae and Clusters of Stars, being the Catalogue of the late Sir John F.W. Herschel, Bart., revised, corrected, and enlarged." (Dreyer J. L. E., 1888, Mem. R. Astron. Soc., 49, 1-237).[1]
NGC 2000.0
NGC 2000.0[2] is a modern compilation of the New General Catalogue of Nebulae and Clusters of Stars (NGC), the Index Catalogue (IC), and the Second Index Catalogue compiled by J. L. E. Dreyer (1888, 1895, 1908). The new compilation of these classical catalogs is intended to meet the needs of present-day observers by reporting positions at equinox B2000.0 and by incorporating the corrections reported by Dreyer himself and by a host of other astronomers who have worked with the data and compiled lists of errata. The object types given are those known to modern astronomy.
See the catalog page for a list of NGC objects.
