William Herschel discovered NGC 6241 = H III-735 on 29 Apr 1788 (sweep 838) and recorded "eF, pS, 300 verified it and shows iF." His position matches CGCG 252-005 = PGC 59085." This is one of the fainter galaxies that WH discovered.

400/500mm - 17.5" (8/22/98): fairly faint, fairly small, elongated 4:3 ~E-W, 50"x35". Weak, even concentration to a slightly brighter core and very faint quasi-stellar nucleus. Picked up while observing Zwicky's Triplet ~7' WNW.

17.5" (6/18/88): faint, fairly small, slightly elongated ~E-W, weak concentration. In a group with UGC 10586 6.7' ESE and "Zwicky's Triplet" = Arp 103 6.6' WNW.

600/800mm - 24" (7/19/12): fairly faint, fairly small, round, 30" diameter, gradually increases to a very small brighter nucleus. UGC 10586 lies 6.7' ESE and Zwicky's Triplet = Arp 103 lies 8' WNW. The UGC appeared faint or fairly faint, fairly small, round, 30" diameter, broad weak concentration (face-on spiral).
