IC 294 = IC 296 = IC 1889. Gary Kronk has been working through Swift's lists of nebulae for his forthcoming book on Swift (published late in 2017, the book is now available). He recently (March 2017) asked about three of the nebulae announced in Swift's 8th list in AN 122, 241, 1889 (whole number 2918), numbers 30-32. These turn out to be NGC 1270 (#30) and NGC 1277 (#32), both of which see, and NPM1G +41.0110 (#31; see NGC 1277 for a brief discussion).

Clearing up these identifications entailed collecting all the nebulae found by Swift on the nights of 11 and 14 September 1888 to test for systematic offsets in RA and Dec. Swift's positions measured on the night of the 11th have just such an offset of -5 +- 2 seconds of time in RA, and -0.2 +- 0.1 arcminutes in Dec. IC 294 and IC 295 were found on this night; applying the correction has moved IC 294 to within less than an arcminute of Swift's position for IC 296 (found just three nights later on the 14th). Both observations thus point at the same galaxy that later picked up yet another IC number, 1889 (which also see). The identification is strengthened by Swift's note about the "F D * nr p". The double, though relatively wide with a separation of about forty arcseconds, is there.
