NGC 1 and NGC 2 as an optical double. NGC 2 is located about 345 million light-years from the Solar System, with a magnitude of +14.2, while the distance to NGC 1 is 210 million light-years. Although visually close in the sky, NGC 1 and NGC 2 are at very different distances; were they stars, they would be referred to as an "optical double" as ...
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.

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.Other objects in the catalogue can be found in the other subpages of the list of NGC objects.
The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use.
It is located 130,000 light-years (40 kpc) [3] from the Andromeda Galaxy's galactic core, and is the brightest [3] (by absolute magnitude) globular cluster in the Local Group, with an absolute visual magnitude of −10.94 and the luminosity of 2 million Suns. [4] It has an apparent magnitude of 13.81 in V band.
The Double Cluster in Perseus (lower left of center, wide angle view) Greek astronomer Hipparchus cataloged the object (a patch of light in Perseus) as early as 130 BCE. To Bedouin Arabs the cluster marked the tail of the smaller of two fish they visualized in this area, and it was shown on illustrations in Abd al-Rahman al-Sufi's Book of Fixed Stars. [4]
Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major. It is the second-largest member of the M81 Group , with the D 25 isophotal diameter of 12.52 kiloparsecs (40,800 light-years ).
Messier 2 or M2 (also designated NGC 7089) is a globular cluster in the constellation Aquarius, five degrees north of the star Beta Aquarii. It was discovered by Jean-Dominique Maraldi in 1746, and is one of the largest known globular clusters.
