History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
IC 1740 may be the double star at 01 49 21.0, -30 10 10 or it may be the double at 01 46 35.4, -30 20 03. The first is closer to Swift's position, but the second is a pair of nearly equally bright stars. That would fit Swift's description considerably better.
Swift makes a great deal of this object (and a near twin, IC 1589, which see) as a close pair of nebulous stars, so Lauberts's suggestion that this one may be NGC 749 is certainly not correct (N749 has no companion, star or galaxy). Swift claims to have seen the object several times at different powers, but given that there is nothing at his position, we can't say for sure just what he did see. I'm leaning toward the second pair noted above, but we may never know for sure.
