History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 7477 is an asterism of two stars superposed on a fainter galaxy close to d'Arrest's position. It is not, as supposed by Burnham (and Dreyer in an IC1 Note), identical to NGC 7472 = NGC 7482 (which see). D'Arrest describes a 17th magnitude star which is attached to his nebula to the north. N7482 has no such star to the north, while the asterism does (there is also an even fainter star to the southeast that d'A did not see).

D'A also discusses Struve's object and suggests that it is identical to his (d'A's). Since Marth's observations had not yet been published when d'A drew up his monograph, this was a reasonable assumption on d'A's part. However, it is probably wrong. Struve's description matches N7482 very well, and d'A's asterism only roughly.


See NGC 7482.
