Guillaume Bigourdan discovered IC 92 = Big. 115 on 2 Nov 1885 with the 12" refractor at Paris. His position is a fairly close match with CGCG 502-029 = PGC 4780. This galaxy has been assumed identical to NGC 468 = h98, discovered by John Herschel on 22 Nov 1827. Herschel's position was 4' south of the galaxy and as a result Dreyer added the comment in the IC "? different from h 98", indicating his uncertainty if IC 92 was the same object.
In March 2015, Harold Corwin checked JH's observing logs (in response to an inquiry from Courtney Seligman about the identity), and found that Herschel made an error in reducing the position of NGC 468 by 37 seconds (recording the wrong wire). Once corrected, his position for h98 = NGC 468 is a close match with NGC 472 = UGC 870, a significantly brighter galaxy than IC 92. So, IC 92 should be the single identity for this galaxy. See NGC 468 for more.
400/500mm - 17.5" (12/23/89): extremely faint, small. A mag 15 star is 1' NW. Located 10' WNW of NGC 472 = NGC 468.
