DeLisle Stewart found IC 4375 = D.S. 393 on an Arequipa plate in 1900 and measured an accurate position. John Herschel probably discovered this galaxy in 1837 and catalogued it as h3558 (later GC 3796 = NGC 5488), but his position was poor. See NGC 5488 for more.

400/500mm - 18" (5/16/09): fairly faint, moderately large, very elongated 7:2 SSW-NNE, 1.8'x0.5', bright core with much fainter extensions. Located close north of mag 9 star HD 123387 (1.2' between centers) that detracts from viewing. The major axis of the galaxy is nearly collinear with the star.
