Lewis Swift discovered NGC 6127 = Sw. IV-29 on 6 Jul 1886 and logged "pF; vS; R." His position matches UGC 10345. He found this galaxy again just 3 weeks later (28 Jul) and recorded it as Sw. IV-30 = NGC 6128. His positions and descriptions are nearly identical, so it seems odd that neither Swift nor Dreyer suggested the equivalence NGC 6127 = NGC 6128.

It's been assumed that this galaxy was first discovered by WH and catalogued as H II- 810 = NGC 6125 with a 20' error in declination. But Wolfgang Steinicke has shown that WH could not have seen this galaxy, as it is too far north in his sweep. Instead, WH II-810 refers to NGC 6130 = UGC 10347.

400/500mm - 17.5" (6/15/91): moderately bright, fairly small, 1.5' diameter, round. Sharp concentration with a small very bright core containing a stellar nucleus, faint round halo.
