CGCG 540-085, which RNGC misidentifies as NGC 1264, is 4.4' SSW. It appeared very faint, extremely small, round, even surface brightness. Three stars forming a right triangle are 2'-3' west.
Guillaume Bigourdan discovered NGC 1264 = Big. 19 on 19 Oct 1884 and noted "mag 13.3, 30" diameter, vslbM." His position corresponds with UGC 2643 = PGC 12270. The RNGC misidentifies CGCG 540-085 = PGC 12254 as NGC 1264. UGC and MCG have the correct identification. Discussed in RNGC Corrections #3 and Corwin's notes.
400/500mm - 17.5" (12/3/88): very faint, small, round, low surface brightness. An extremely faint companion is 1.5' SSW. Member of AGC 426.
600/800mm - 24" (2/15/18): at 375x; fairly faint, fairly small, slightly elongated SW-NE, 0.5'x0.4', very small slightly brighter nucleus. The nearest member of AGC 426 is PGC 12263, 1.4' S, which was extremely faint and small, 10" diameter, required averted to pick up. 5' to the SE are PGC 12292 and 12294, a close pair of mag 15V galaxies adjacent to a mag 11.5 star.
