Stephane Javelle discovered IC 1070 = J. 1-327 on 3 Jun 1891 with the 30-inch refractor at the Nice Observatory and recorded "vF, S, R, diffic."
600/800mm - 24" (6/23/17): at 375x; faint, very small, slightly elongated NW-SE, 15"x12", weak concentration. Located 4' SSW of NGC 5775.
24" (7/14/15): at 375x; faint to fairly faint (visible continuously), small, elongated 3:2 NW-SE, 18"x12". By far the faintest and smallest in a trio with NGC 5774 3.9' NE and NGC 5774 6.3' NNW.
900/1200mm - 48" (4/19/17): moderately bright, fairly small, oval 3:2 NW-SE, brighter core but no sharp nucleus. Located 4' SSW of NGC 5775, which forms a striking pair with NGC 5774.
