IC 2492, like IC 2485 (which see; it is the only other object that Stewart found on one-hour Arequipa Bruce plate 4240) may be a defect. Stewart's description reads, "cF, vS, R, B * 1' np, susp." In this case, however, there is a faint galaxy about 2.5 arcmin northeast of Stewart's nominal position. This is usually taken as IC 2492 even though it is obviously elongated, not round as Stewart describes his object.

But Stewart's "bright" star is not where he claims it to be. There is a relatively faint star about an arcmin northeast of the galaxy, but I do not think that this is Stewart's star. It seems more likely to me that either Stewart made an error in measuring the object's position, or that both it and the "star" are defects.

So, I'm clearly not convinced that the galaxy is the one that Stewart saw. And I'd just as clearly like to see the Harvard plate. In the meantime, I'm leaving a question mark on the IC number.
