Lewis Swift discovered IC 598 = Sw. VIII-51 on 27 Mar 1889 and reported "vF; vS; R; BM. Almost stellar." There is nothing at his position, but 6.6' SSW is UGC 5502, the brightest nearby galaxy. This is almost certainly IC 598, though I'm surprised Swift called it round as it was clearly elongated.

600/800mm - 24" (4/13/18): at 200x and 375x; moderately bright and large, elongated 3:1 N-S, 1.0'x0.35'. Contains a small high surface brightness core with much fainter wings N-S. Located 49' WNW of mag 3.4 Lambda UMa (Tania Borealis).
