Deep Sky Catalogs

The NGC catalog contains a large collection of deep sky objects compiled during the 18th and 19th centuries, including galaxies, nebulae, and clusters.

The IC catalog is an important supplement to the NGC, adding more deep sky objects discovered in the late 19th and early 20th centuries.

Includes 110 of the brightest and most iconic deep sky objects, ideal for amateur astronomers using small telescopes.

Includes 109 curated deep sky targets for amateur observers, including many southern sky objects not covered by the Messier catalog.
