On the DSS and SDSS, IC 1575 appears to be a post-merger system with a prominent curving dust slicing the galaxy from SW to NE and low surface brightness outer arcs or shells. The NW portion of the system contains the bright nucleus and is listed in NED as IC 1575A = MCG -01-03-002 and the larger SE portion is IC 1575B = MCG -01-03-003.

Lewis Swift discovered IC 1575 = Sw. XI-5 on 5 Sep 1896 and reported "eeF; S; R; 10m * close s[outh]; not [NGC] 239." His position is 1.8' too far south.

600/800mm - 24" (9/1/16): at 322x; fairly faint, fairly small, irregularly round, ~25" diameter. A mag 13.3 star is 0.6' S. At the northwest side is a brighter quasi-stellar knot or nucleus of IC 1575A.
