Albert Marth discovered NGC 7745 = m 590 on 6 Sep 1863 and measured an accurate position. MCG (+04-56-004) fails to use the NGC designation and as a result the RNGC doesn't reference the MCG.

400/500mm - 17.5" (12/16/95): extremely faint, very small, round, 20" diameter. Appeared as a very low surface brightness spot that required averted vision. Collinear with a wide pair of mag 13/14 stars 3.0' and 4.0' NW of center. Located 15' SE of NGC 7741.
