Lewis Swift discovered IC 3010 = Sw. XI-134 on 11 Apr 1898 and noted "eeeF; cS; R; D * sf; v diff." Based on an observation in 1900 with the 20" refractor in Denver, Herbert Howe reported "the "D * sf" is of mags 10-10.5, angle 45°, and distance 40"; it is 8' from the nebula. Just south of the nebula, and pointing at it is a row of five stars of average mag 11.5, the farthest being less than 10' away [mentioned in my observation]. The nebula is considerably brighter than the description "eeF, v diff." would imply."

400/500mm - 18" (5/28/06): fairly faint, moderately large, round, fairly low surface brightness, 1' diameter, broad concentration to an ill-defined core. A 9' string of a half-dozen mag 13/14 stars extends to the south-southwest from the galaxy. Located 38' SE of IC 3010.
