All other Messier objects were assigned with NGC numbers also, and in some cases, parts of them got additional numbers, so that not every NGC or IC entry is visible from the Messier List "sorted by Right Ascension". Here we give a hopefully complete list of NGC and IC numbers related to Messier objects. Please email me any corrections, possible omissions, or comments !
Also look at our Messier Object Cross Reference list with other catalog assignments of Messier's objects.
