Stephane Javelle found IC 1710 = J. 3-888 on 18 Jan 1896. His position matches UGC 1081 = PGC 5634. This galaxy was discovered earlier by Stephan on 17 Oct 1876, but due to a transcription error by Dreyer, its NGC position is two degrees too far north. So, NGC 575 = IC 1710. CGCG, UGC and MCG use the IC designation based on position, although NGC 575 should apply based on historical discovery. Karl Reinmuth, in his 1926 survey based on Heidelberg plates, noted the equivalence of NGC 575 with IC 1710. See Corwin's notes.

400/500mm - 17.5" (11/30/91): faint, fairly small, round, 1.0' diameter, low almost even surface brightness, broad mild concentration, edges fade into background.
