IC catalog

Index Catalogue of Nebulae and Clusters of Stars. Published by J. L. E. Dreyer in the 1880s as two appendices to the New General Catalogue. It summarized the discoveries of galaxies, clusters and nebulae between 1888 and 1907.
I do not intend to place the whole catalog here, just objects that are of interest to me with the potential of imaging or part of the Messier catalog.

IC434

IC2118 - Witch Head Nebula

IC4725
