NGC 2000.0 (also known as the Complete New General Catalog and Index Catalog of Nebulae and Star Clusters) is a 1988 compilation of the NGC and IC made by Roger W. Sinnott, using the J2000.0 coordinates. [17] [18] It incorporates several corrections and errata made by astronomers over the years. [5]

The following is a list of NGC objects, that is objects listed in the New General Catalogue (NGC). It is one of the largest comprehensive astronomical catalogues for deep sky objects such as star clusters, nebulae, and galaxies. List of NGC objects (1–1000) List of NGC objects (1001–2000) List of NGC objects (2001–3000)
This is a list of NGC objects 1–1000 from the New General Catalogue (NGC). The astronomical catalogue is composed mainly of star clusters, nebulae, and galaxies.

The GC contained 5,079 entries. Later, a complementary edition of the catalog was published posthumously as the General Catalogue of 10,300 Multiple and Double Stars. The small "h" followed with the catalogue entry number represented the item. [4] In 1878, John Louis Emil Dreyer published a supplement to the General Catalogue. [6]
This is a list of NGC objects 6001–7000 from the New General Catalogue (NGC). The astronomical catalogue is composed mainly of star clusters , nebulae , and galaxies . Other objects in the catalogue can be found in the other subpages of the list of NGC objects .
Unlike objects in the Messier catalogue, which are listed roughly in the order of discovery by Messier and his colleagues, [5] the Caldwell catalogue is ordered by declination, with C1 being the most northerly and C109 being the most southerly, [1] although two objects (NGC 4244 and the Hyades) are listed out of sequence.
