NGC and IC numbers associated with Messier Objects -

NGC and IC numbers associated with Messier Objects

There are four Messier objects which have no NGC number assigned

(see ):

M25 (which is IC 4725),

the double star M40,

the Pleiades M45

(some of their nebula have NGC numbers, however)

and the Milky Way Patch M24

(which contains open cluster NGC 6603 though).

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.
