Caldwell Catalog of 109 Deep-Sky Objects

Caldwell 109 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 in modest telescopes. Astronomy clubs and star parties sometimes host "half-marathons" where the goal is to find half the objects in a single night.

Also see the related Messier Catalog 110 Objects and the more difficult Herschel 400 Objects.
