Albert Marth discovered NGC 7239 = m 470 on 1 Oct 1864 and noted "eF, vS." There is nothing at his position but 1 minute of RA west is PGC 68388. A single digit error in time would account for the discrepancy.

400/500mm - 17.5" (8/10/91): very faint, very small, round, bright core. Three star mag 14-15 stars on a line are close south including a mag 14 star 1.4' S and a faint mag 15 star 2.2' S.
