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.

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.
This is a list of NGC objects 1001–2000 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 .
NGC 2371-2 is a dual lobed planetary nebula located in the constellation Gemini.Visually, it appears like it could be two separate objects; therefore, two entries were given to the planetary nebula by John Louis Emil Dreyer in the New General Catalogue, so it may be referred to as NGC 2371, NGC 2372, or variations on this name.

Messier 38 or M38, also known as NGC 1912 or Starfish Cluster, [4] is an open cluster of stars in the constellation of Auriga. It was discovered by Giovanni Batista Hodierna before 1654 and independently found by Le Gentil in 1749.
NGC 2848 is an intermediate spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 2,361 ± 23 km/s, which corresponds to a Hubble distance of 34.82 ± 2.46 Mpc (∼114 million light-years). [1] It was discovered by German-British astronomer William Herschel on 31 December 1785.
This value gives the logarithm of the abundance relative to the Sun; the actual proportion is 3.2–4.6% of the solar abundance. Messier 3 is the prototype for the Oosterhoff type I cluster, which is considered "metal-rich".
