This is a partial list of IC objects, which are astronomical objects included in the Index Catalogue of Nebulae and Clusters of Stars. This two volume catalog was published in 1895 and 1908 by J. E. L. Dreyer. The constellation information for this table is available from the NGC2000.0: Complete New General Catalog and Index Catalog. [1]
Articles with the IC number in the title use [[Category:IC objects|####]], dropping the IC prefix, and using only the number. The number should be padded up to 4 digits using zeroes. Articles without the IC number in the title use [[Category:IC objects]]. A redirect containing the IC number should also be added to the category, sorted as above.

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.
Speed sensors are machines used to detect the speed of an object, usually a transport vehicle. They include: Wheel speed sensors; Speedometers; Pitometer logs; Pitot tubes; Airspeed indicators; Piezo sensors (e.g. in a road surface) LIDAR; Ground speed radar; Doppler radar; ANPR (where vehicles are timed over a fixed distance)
Ben — Jack Bennett's catalogue of 152 deep-sky objects in the southern celestial hemisphere, all from the NGC or IC lists, except Ben 47 which is Melotte 105 in Carina, and Ben 72a which is Trumpler 23 in Norma; Bergeron — Joe Bergeron (for example: Bergeron 1 in Cepheus) [9] BFS — Blitz-Fitch-Stark (for example: BFS 15 in Cepheus) [10]
IC 4461 is a spiral galaxy located in the Boötes constellation, located at distance of 417 million light-years from both the Milky Way and Andromeda Galaxy. [ 3 ] [ 4 ] [ 5 ] The galaxy was first discovered by Stephane Javelle on June 22, 1895 who found it as a faint and round object. [ 6 ]
IC 2560 is a spiral galaxy lying over 110 million light-years away from Earth in the constellation of Antlia. It was discovered by Lewis Swift in 1897. [3] The luminosity class of IC 2560 is II [4] with a broad HI line [5] containing regions of ionized hydrogen. Moreover, IC 2560 is an active Type 2 Seyfert Galaxy. [6]
