IC 4922 is most likely a plate defect. Stewart recorded it on a one-hour Bruce plate, so it would had have to have been fairly bright to show up there. He described it as "vF, vS, R, susp", the "susp[ected]" meaning that he found it on only that one plate.

There is a galaxy cluster a few arcmin south of his position, but the brightest objects in it are around 17th magnitude, too faint to have been picked up on a "short" exposure plate.
