The Caldwell catalogue

Patrick Moore noticed that Messier's list, compiled from Paris, misses some of the best objects in the sky — the whole southern hemisphere among them — and in 1995 published 109 more to fill the gap. He numbered them by declination, from the far north to the far south, and used the C of Caldwell because Messier had already taken the M.

NOT IN THIS CATALOGUE
4 entries are missing here — C 9, C 14, C 41, C 99. They are objects the upstream catalogues this site merges do not carry as a single row, usually because they are a naked-eye asterism or a pair of clusters catalogued separately.
