400/500mm - 17.5" (12/19/87): moderately bright, fairly small, round, bright core, faint stellar nucleus. Forms a pair with UGC 2626 3.7' NE. Member of AGC 426.

17.5" (12/3/88): fairly faint, fairly small, round, small bright core.

600/800mm - 24" (2/15/18): at 375x fairly bright, moderately large, round, ~45" diameter, strong concentration with a bright core that increases to an intense quasi-stellar nucleus. Located at the southwest end of the mainline of AGC 426. UGC 2626 is 3.7' NE and NGC 1259 is 7.4' NE. A mag 14.5 star is 1.3' SW.
