IC 1760 = IC 1759. The position for No. 30 in Swift's 11th collection (in AN 3517) of new nebulae is one degree too far north. The object originally appeared in his 5th list of nebulae found from Lowe Observatory (it is number 8), and actually has the correct declination in the AN version of that list. Unfortunately, Swift apparently copied it from the AJ version, so its IC position is wrong. Dreyer noted the discrepancy, though he omitted Swift's note "Cordoba 681 sp." That is wrong, too, though -- CD -33 681 is southeast of the galaxy, not southwest. However, the star number clinches the declination, and therefore the identification -- the stars at this RA in the -32 zone have numbers in the range of 740 to 760.

The declination of IC 1759 is roughly correct (it is 3 arcmin off), though the RA, like that of IC 1760, is 25 seconds too small.
