400/500mm - 17.5" (7/21/90): faint, small, slightly elongated 4:3 NW-SE, even surface brightness. A mag 15.5 star is at the SE end. Located 3.1' ENE of a mag 8 SAO 101868. IC 1161 lies 12' ESE. Member of AGC 2147.

600/800mm - 24" (8/12/18): at 260x; faint, fairly small, slightly elongated, low nearly even surface brightness with a very wea concentration. Located 3' ENE of a mag 8 star (HD 143551). Forms an equilateral triangle with a mag 12.8 star 2' E and a similar star 2' N.

24" (6/13/15): fairly faint, fairly small, slightly elongated, 30"x25". A mag 15.8 star was noted just off the east-southeast edge [34" from center]. Located 3.1' ENE of mag 7.9 SAO 101868. IC 1161 is 10' ESE and CGCG 108-038 is 6' NW.

24" (6/28/14): faint to fairly faint, moderately large, slightly elongated, 40" diameter, weak concentration, fairly low surface brightness. A mag 15.8 star is 30" SE of center, just off the edge. Situated 3.2' ENE of mag 7.9 HD 143551, which interferes a bit with viewing. Member of AGC 2147.
