Stephane Javelle discovered IC 539 = J. 2-636 on 9 Mar 1893. His position is good.

600/800mm - 24" (2/8/18): at 375x; fairly faint, fairly small, slightly elongated ~25"x20", weak concentration with slightly brighter nucleus. Two small chains of mag 13 and fainter stars extend to the north and northwest. IC 539 is located 13' N of mag 4.9 Tau1 Hya. A mag 7 companion is 1.1' to its north and the pair (cataloged as HJ 1167) is collinear with the galaxy.
