Lewis Swift discovered NGC 6376 = Sw. IV-50, along with NGC 6377, on 1 Sep 1886, and recorded "eeF; eS; R; e diff; sf of 2 [with NGC 6377]." His position is fairly close and the relative offsets for the pair are accurate.

400/500mm - 17.5" (6/18/88): very faint, very small, slightly elongated, weak concentration. Forms an interacting pair with NGC 6377 35" NE of center.

600/800mm - 24" (7/20/17): at 375x; fairly faint, small, slightly elongated ~N-S, 15"x10", no core or zones. NGC 6376 is the fainter of an interacting pair with NGC 6377 [0.6' NE of center]. On the SDSS this is a highly distorted galaxy with numerous blue knots of star formation.

LEDA 2582497 (= MAC 1725+5845), situated 3.5' SSW, appeared very faint, very small, round, 12"-15" diameter, low even surface brightness. The bright mag 9.8 star 2' NW interferes a bit with viewing.
