Édouard Stephan discovered NGC 6783 = St IV-2 on 4 Aug 1872. His offset points to CGCG 256-013, though Esmiol made a digit error in his 1916 re-reduction and the RA is 1.0 minute too small. Bigourdan noted the galaxy was barely seen.

400/500mm - 17.5" (8/10/91): very faint, small, elongated 4:3 NW-SE, weak concentration. A mag 15.5 is at the SE edge 13" from the center and a mag 15 star is 20" off the NW edge.
