William Herschel discovered NGC 1576 = H III-587 = h314 on 28 Nov 1786 (sweep 640) and reported "vF, S, bM, between 2 stars." His position (Auwer's reduction) was 1' too far NW. There are two stars that bracket the galaxy as in the description.

400/500mm - 17.5" (2/1/92): fairly faint, small, slightly elongated 4:3 SW-NE, well-defined bright core, faint stellar nucleus. Almost at the midpoint of two mag 13 stars 1.2' SE and 1.5' WNW.
