William Herschel discovered NGC 5768 = H III-373 on 14 Apr 1785 (sweep 400) and recorded "vF, just north of a small star, which it seems to be an electrical brush preceding towards the north, but there is a little distance between the star and the brush. At first sight it resembles the 1st of my Fanshaped." On 23 Mar 1789 (sweep 917) he logged, "F, R, faint nucleus, vF chevelure north of a small star; the chevalure reaches up to it."

200/250mm - 8" (6/30/84): very faint, small, almost round, even surface brightness. A faint star is on the south edge. Two stars to the east and SE form an equilateral triangle. Mag 5 11 Librae lies 25' NW.

400/500mm - 17.5" (6/18/93): fairly faint, fairly small, elongated 4:3 WNW-ENE, 1.2'x0.9', fairly even surface brightness. A mag 12.5 star is attached at the south edge 0.5' from center. Located 25' SE of 11 Librae (V = 4.9).
