The Index Catalogue (IC) —also known as the Index Catalogue of Nebulae, the Index Catalogue of Nebulae and Clusters of Stars, IC I, or IC II— is a catalogue of galaxies, nebulae and star clusters that serves as a supplement to the New General Catalogue. It was first published in 1895, and has been expanded to list 5,386 objects, known as the IC objects.
The catalogue was compiled by J. L. E. Dreyer in the 1880s, who published it as two appendices (IC I[1]& IC II[2]) to the New General Catalogue. It summarized the discoveries of galaxies, clusters and nebulae between 1888 and 1907.
