Caldwell Catalogue

Sir Patrick Caldwell-Moore (1923-2012) was an eminent English amateur astronomer. Perhaps best known as the presenter of the BBC's television programme The Sky At Night, Sir Patrick was also a prominent author and researcher. He compiled the Caldwell Catalogue as a complement to the well-established Messier Catalogue, noting that the Messier Catalogue did not include many of the sky's brightest deep sky objects, nor many objects from the southern hemisphere.

Since the initial M was already in use for Messier objects, Sir Patrick used his other surname, Caldwell, to provide the initial C for the items in his Caldwell Catalogue.
