Albert Marth discovered NGC 6570 = m 363, d'A on 2 Jun 1864 and noted "pF, pL, R." His position and description matches UGC 11137. Heinrich d'Arrest independently found NGC 6570 on 23 Aug 1865 with the 11-inch refractor at Copenhagen and observed the galaxy on 3 consecutive nights. E.E. Barnard found this galaxy again on 15 Aug 1911 while observing Wolf's periodic comet 1911a. After reducing the position he realized the nebula was Marth's NGC 6570.

400/500mm - 17.5" (7/1/89): fairly faint, oval SSW-NNE, fairly small, very weak concentration, rich star field. Bracketed by four mag 13-14 stars.
