IC 2485 is probably a defect on Stewart's plate. He describes it as "eF, vS, R, like several sts inv in neb, susp." There is nothing at his position that matches this description unless the defect appears around one of the several asterisms of double or triple stars in the area.

In my SGC workbook, I noted "No neb, but cl?" The cluster, however, is large, at least 15 arcmin by 10 arcmin, and is composed of stars that are fairly bright (10th to 12th magnitude). This is clearly not Stewart's object.

Once again, an examination of the original Harvard plate (4240) is called for. This is a one-hour plate; the only other object that Stewart found on it is IC 2492, which see for a story of its own.
