Albert Marth discovered NGC 6270 = m 323 = St II-9 on 28 Jun 1864 and noted "eF, S, R." His position is 5' north of PGC 95562. Édouard Stephan independently found this galaxy on 22 Jul 1871 and reported an accurate position in discovery list II-9.

The RNGC and PGC misidentify MCG +05-40-015 = PGC 59362 as NGC 6269. This galaxy is located 16' south of Stephan's position! Because of this error, the NGC 6270 is not included in the original PGC but has a HyperLeda designation (and no NGC label) of 95562. I mentioned this error in RNGC Corrections #4.

400/500mm - 17.5" (7/27/95): very faint, very small, slightly elongated E-W, 20" diameter. Very weak concentration with an occasional very faint stellar nucleus. Can hold steadily with averted vision although not included in the UGC, MCG or CGCG. Located 10' E of NGC 6269 in the AWM 5 group (6th of 8). Misidentified in the RNGC.
