NGC/IC Project Restoration Effort

===== NGC 7610 and NGC 7616 are two of the objects found by Ainslee Common with his 36-inch reflector. His positions coincide with nothing on the sky, but close to the position for NGC 7610 is a relatively large Scd galaxy that might well have been described as "diffused" by him. There is nothing at all near the position for NGC 7616, and I suspect that Common's two observations refer to the same object. This galaxy has been micrometrically measured by Kobold. His second measurement, reported under the number NGC 7610, was corrected on his errata page. The corrected measurement is obviously a repeat measure of the same object as his first measure, listed under NGC 7616. He therefore added a note to that effect, saying that the measured object was "most likely" to be NGC 7616. I think this is because Common's description is "pF, difffused" for N7616, but "F, S, difffused" for N7610. Bigourdan has no observations for either object, though he reports having seen NGC 7610 at its NGC position. Carl Wirtz also provides only a description for it, and includes the object under the number "NGC 7616?" in his collection of the Strassberg micrometric positions. The galaxy was subsequently ignored until its appearance in CGCG, MCG, UGC, and the 10th KUG list. Steve Gottlieb reports a visual sighting of it in 1992, but could find nothing near the position of NGC 7616. He pointed out, though, a very faint galaxy a few seconds of time east of the NGC position; I doubt that Common could have seen this, even with a 36-inch. If it were N7616, then Common's descriptions would be backwards: "F" for the much brighter galaxy, and "pF" for the much fainter.

===== NGC 7610 17.5" (8/27/92): faint, moderately large, 1.5' diameter, low surface brightness, no central concentration. A mag 12 star is just off the southwest edge 1.1' from the center. Located at the north edge of the Pegasus I cluster.
