Albert Marth discovered NGC 7266 = m 476 on 1 Oct 1864, along with NGC 7257 = NGC 7260, and noted "F, vS, R, alm stellar." There is nothing at his position though this galaxy is 25 seconds of RA east and 5.7' south. Harold Corwin notes that despite the poor positional match, the same offset helps to identify NGC 7257, found the same night. Bigourdan measured an accurate position on 5 Nov 1887 and the correction was given in the IC 2 Notes.

400/500mm - 17.5" (8/7/91): fairly faint, fairly small, round, broad concentration, faint stellar nucleus. Located 5.4' SW of mag 9.5 SAO 146069.
