Astronomy:List of IC objects

Short description: none

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] In some cases, the NASA/IPAC Extragalactic Database was used to confirm cross-identifications of galaxies.^[2] The remaining data is from the SIMBAD Astronomical Database^[3] unless otherwise noted.
