List of Common Deep Sky Catalogs

Below is a listing of the various more and less common catalogs of deep sky objects, together with abbrevations and a short description. This list is of course far from being comprehensive. If you have any comments or additions, please email me.

We have some of these catalogs available here at SEDS. Other compilations are acknowledged where they are linked.

Besides these catalogs which are often used to designate objects, there are many observing lists and catalogs suitable for work-through and as databases, as well as historic deepsky catalogs, which we do not include here.


M: Messier
Charles Messier's Catalog of 110 objects. First more reliable and comprehensive catalog of deep sky objects, must-see for amateurs.
NGC: New General Catalog
J.L.E. Dreyer. New General Catalogue of Nebulae and Clusters of Stars Mem. Roy. Astron. Soc. 49, Part I (1888). Reprinted 1912 and 1953. Attempt to compile a comprehensive list of all deep sky objects known at that time, including the catalogs of the Herschels and Lord Rosse. Most of these objects had been discovered visually.
IC: Index Catalog
J.L.E. Dreyer. Index Catalogue of Nebulae Found in the Years 1888 to 1894, with Notes and Corrections to the New General Catalogue, Mem. Roy. Astron. Soc. 51, 185 (1895), and Second Index Catalogue of Nebulae Found in the Years 1895 to 1907; with Notes and Corrections to the New General Catalogue and to the Index Catalogue for 1888 to 1894, Mem. Roy. Astron. Soc. 59, Part 2, 105 (1908), both reprinted 1912 and 1953. Many IC objects had been discovered photographically.
Note: NGC, IC and Messier objects can be accessed interactively by the SEDS Interactive NGC Online Catalog.

Less common general catalogs:

Classified in 8 subclasses, and numbered in the order of discovery for each subclass (e.g., H I.215 or H 1.215, H II.909 or H 2.909, H VIII.88 or H 8.88; older notations were like H 215-I or H 215^I or I H 215).

HP: Haute Provence
Pal: Palomar (from Adventures in Deep Space)
15 very faint globular clusters discovered within the POSS (Palomar Observatory Sky Survey). At least some are observable with large aperture amateur instruments, though. Pal 1-13 from Table I in: Abell G.O., 1955. Globular Clusters and Planetary Nebulae Discovered on the National Geographic Society-Palomar Observatory Sky Survey. Publications of the Astronomical Society of the Pacific, Vol. 67, No. 397, p.258 (August 1955) - Table II is in the Abell Catalog of Planetary Nebulae. Added later: Pal 14 = Arp 1 = C 1608+150 (1960), Pal 15 = An. (Zwicky) = C 1657-004. Palomar 12 was once thought to be a nearby dwarf spheroidal galaxy (Capricornus Dwarf).
Ter: Terzan (from Adventures in Deep Space)
11 globulars discovered by Agop Terzan (France) in the infrared; mostly heavily obscured and situated near the Galactic Center. Originally 12 entries, of which the original Terzan 11 was a rediscovery of Terzan 5; newer lists renumber the original Terzan 12 as Terzan 11. Terzan 7 and 8 are probably members of the Sagittarius Dwarf Elliptical Galaxy. Mikkel Steine suggests that Terzan 3 and Terzan 6 and possibly Terzan 10 may be open clusters. References:

UKS: UK Schmidt
Three globular clusters were cataloged under UKS designations, one of them, (UKS 1751-241) is frequently referenced as UKS-1, while UKS 1636-283 (ESO452-SC11) was sometimes referred to as UKS-2. A third reference, UKS 0923-545 is no more in the current list of Milky Way globular clusters.
