IC 2169 = IC 447. Neither of Barnard's positions is particularly good, though we can get close to the apparent center of his large, diffused nebulosity if we adopt his RA for IC 447 and his Dec for IC 2169. Even though his two positions are more than 10 arcmin apart, they clearly refer to the same object: it is big (I make it about 30 x 30 arcmin on the DSS). Barnard notes "several stars 9-10 involved"; those stars are indeed there.

This and IC 2167 = IC 446 (which see) were not published by Barnard, but were among those objects whose positions were sent directly to Dreyer. I'm a bit surprised that one or the other of them did not catch the identities before Dreyer published the second IC.

Some years after I wrote the above paragraph, Dave Riddle alerted me to Barnard's original publication (see IC 2167 above) where he did in fact publish descriptions and positions of the two IC1 nebulae. Interestingly, Barnard also retracted his discovery of IC 447 in Lick 11 (again, see IC 2167), incorrectly claiming it to be identical to NGC 2245 (which see for the story). The NGC object is a small, fairly compact nebula northeast of the much larger, more diffuse IC object.
