IC 2545 may be the very faint double star at Stewart's position. It matches his description exactly: "eF, eS, cE 25 deg, triangle with 2 F stars." But I'm astonished that he could see such a faint, tiny object, even on a 4-hour exposure (plate 4342). So, I've put a colon on it in the position table (I previously had a question mark, but the suitability of Stewart's description is seductive).

Andris Lauberts and Wolfgang Steinicke also had trouble believing that the double is the one Stewart found. They both picked a much brighter object 30 seconds preceding and 2 arcmin south of Stewart's nominal position. This, however, does not match Stewart's description at all, particularly with respect to the two stars. However, I'm including it in the table because it is bright enough for Stewart to have picked up easily.

This is also obviously a candidate for examination on the original plate.

Another note: When I first examined IC 2545, I mistook the double star for a faint galaxy on the IIIa-J plate. However, closer examination of the object on the 2MASS images shows that it is indeed a double star.
