NGC4631 (Best 38, Caldwell 32) is a spiral galaxy located 6.4° SSW of Cor Caroli (alpha Canum Venaticorum), and located in the top, right of the photograph. Dreyer calls it very bright (mag. 9.3), very large (14'x2'), and very elongated (PA 86°). It has a bright, slightly off-center nucleus with a star just north of it. NGC4627 is the small galaxy just 2'-3' to the north. NGC4656 (Best 39) is the other large galaxy to the lower, left. Described as fairly bright (mag. 10.6), large (15'x3'), and very elongated (PA 34°), it, too, has a faint companion to the north (NGC4657) that is partly superimposed.
