John Herschel discovered NGC 5794 = h1891 on 13 May 1830 and recorded "pF, S, vsbm to a *13m; the first of 3 in a line [with NGC 5797 and 5804]. A star 6.7 mag near." His position is 3' too far south, although he marked the declination uncertain. This galaxy and NGC 5797 are the only two galaxies in the group with a decent position in the RNGC.

400/500mm - 17.5" (6/18/93): fairly faint, fairly small, round, weak concentration. First and slightly inferior of three on a line with NGC 5797 5.3' ESE. Located 8' NW of mag 5.6 SAO 45288.
