John Herschel discovered NGC 3454 = h790 on 17 Mar 1831 (sweep 334) and recorded "pF; lE; the np of two [with NGC 3455]. His position matches UGC 6026 = PGC 32763, although I'm surprised he didn't describe this galaxy as very elongated.

R.J. Mitchell, observing on 28 Mar 1856 with LdR's 72", called it "the n one is a long narrow ray np-sf."

400/500mm - 17.5" (4/18/87): fairly faint edge-on streak 5:1 WNW-ESE, fairly small, slightly brighter along the major axis. Forms a pair with NGC 3455 3.6' S. Located 1.7' NNW of a mag 10.5 star.

600/800mm - 24" (2/22/14): moderately bright and large, thin edge-on 5:1 WNW-ESE, 1.4'x0.3', weak concentration, tapers at the tips. Forms a striking pair with NGC 3455 3.6' S, with a mag 10.5-11 star directly between the pair.
