DeLisle Stewart discovered IC 5175 = DS 739, along with IC 5174, on a plate taken in 1899 at Harvard's Arequipa station. He noted "eF, eS, R, bM."

600/800mm - 24" (10/1/16): fairly faint, small, elongated 2:1 E-W, 24"x12", contains a very small brighter nucleus. A mag 10.4 star is 50" SW. Forms an interacting pair with IC 5174 at 2.6' SSW, but the companion was not picked up.
