NGC 6473
NGC 6473 is a single star in the constellation Dragon ( right ascension : 17: 46: 54.0; declination : +57: 18: 30). It was mistaken for another galaxy by Lewis A. Swift on July 22, 1886 during an observation of NGC 6474 and thus gained an entry in the catalog.
Swift's notes from the night of July 22, 1886 ("eeF, S, R, s of 2" for NGC 6473 , "eF, pS, R; 3 sts in a line near and 3 others in a line point to it; e diff; n of 2 "for NGC 6474 ) refer to two different objects and are also too different to describe the same galaxy despite almost identical position information. The acceptance of some modern catalogs that refer to NGC 6474 as NGC 6473 is therefore to be rejected.
