Stephane Javelle discovered IC 19 = J. 1-12, along with IC 18, on 31 Aug 1892. He noted "R, 20" diameter, stellar [nucl] = 14m." and measured an accurate position.

600/800mm - 24" (9/15/12): at 322x appeared fairly faint, fairly small, slightly elongated, 25" diameter, weak even concentration. Brighter of pair (Arp 100) with IC 18 3.4' NNW. Located nearly at the midpoint of mag 7.4 HD 2438 and mag 7.4 HD 2553 (17' separation WSW-ENE).

900/1200mm - 48" (10/25/14): at 488x; fairly bright, fairly small, slightly elongated SW-NE, , 25'x 20", bright core, stellar nucleus. Brighter (higher surface brightness) of an interacting pair with IC 18 3.4' NNW.
