Ralph Copeland discovered NGC 3743 on 18 Mar 1876, just west of "Copeland's Septet", and recorded "F, S, R, from *9 [offset of] 78" in PA 322.5°. This offset points exactly to CGCG 126-106 = PGC 35855, although the galaxy was positioned much too close to Copeland's Septet on the constructed sketch of 13 Apr 1876 because of a confusion with the offset stars.

400/500mm - 18" (5/12/07): very faint, extremely small, round, 12" diameter. Located 1.4' NW of a mag 10 star. Discovered on the same night as Copeland's Septet (13 April 1876) and located 30'-35' SW of the Septet.
