Albert Marth discovered NGC 7546 = m 547 on 1 Oct 1864 and noted "eF, S, lE." His position matches MCG -01-59-007 = PGC 70820 to within 1'. Harold Corwin agrees with this identification but notes that NGC 7546 could be MCG -01-59-008, a fainter galaxy 2' north. This seems unlikely to me as I didn't notice it while viewing -007 with my 17.5".

300/350mm - 13.1" (9/29/84): very faint, very diffuse, fairly small. Located 10' WNW of NGC 7556.

400/500mm - 17.5" (8/1/87): extremely faint, fairly small, almost round, can barely hold steadily with averted. Located in the NGC 7532-7556 group with NGC 7556 10.3' ESE.

600/800mm - 24" (9/29/16): at 375x; faint or fairly faint, fairly small, elongated ~4:3, 0.4'x0.3', irregular shape. A knot or the core seems offset towards the north side. Forms a close pair with MCG -01-59-008 2' N. The companion appeared very faint, fairly small, very elongated 3:1 NNW-SSE, 25"x8", even surface brightness. Located 10' WNW of NGC 7556 in a large group of galaxies.
