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 more than 5,000 objects, known as the IC objects.
