Caldwell Catalog
Caldwell Catalog of 109 Deep-Sky Objects

109 Caldwell deep-sky objects

The Caldwell catalog contains 109 primarily southern-sky deep-sky objects (galaxies, nebulae, and star clusters) that are not too difficult to see using good binoculars and modest-sized telescopes. Astronomy clubs and star parties sometimes host "half-marathons" where the goal is to find half the 109 objects (C1 thru C109) in a single night.

Also see the related Messier Catalog and the more difficult Herschel 400 Catalog.
