Stephane Javelle discovered IC 109 = J. 1-56, along with IC 103 and 105, on 5 Nov 1891 and recorded "pretty bright, round, 10" diameter." His positions are all offset ~1' to the northwest, but the identifications are certain.

600/800mm - 24" (9/23/17): at 375x; faint, small, slightly elongated, low surface brightness, 25" diameter, very weak concentration. A mag 14.7 star is 1.6' W and a mag 15.4 star is off the west side [0.6' from center]. Third in a trio with IC 105 6.7' WNW and IC 103 9' WSW.
