The Caldwell Catalogue

The Caldwell Catalogue is an astronomical catalogue of 109 bright star clusters, nebulae, and galaxies for observation by amateur astronomers. The list was compiled by Patrick Caldwell-Moore as a complement to the Messier Catalogue. The Messier Catalogue is used frequently by amateur astronomers as a list of interesting deep-sky objects for observations, but Moore noted that the list did not include many of the sky's brightest deep-sky objects, including the Hyades, the Double Cluster (NGC 869 and NGC 884), and NGC 253. Moreover, Moore observed that the Messier Catalogue, which was compiled based on observations in the Northern Hemisphere, excluded bright deep-sky objects visible in the Southern Hemisphere such as Omega Centauri, Centaurus A, the Jewel Box, and 47 Tucanae. He quickly compiled a list of 109 objects (to match the number of objects in the Messier Catalogue) and published it in Sky & Telescope in December 1995.

All of the Caldwell objects are visible with binoculars or small telescopes (under favourable conditions), they are popular viewing objects for amateur astronomers. For more information on Patrick Moore see his entry in Wikipedia.
