IC 5004 = NGC 6923. Swift found this galaxy in July of 1897. As with other nebulae found that summer (see e.g. IC 4946 and IC 5003), his declination and description are appropriate, but his RA is off, in this case by 6 minutes of time. John Herschel's position and description for NGC 6923 are good.
ESO speculates that the IC number applies to the same object (a star) as I5003, but with a 1 degree error in declination. This is unlikely as Andris Lauberts did not have Swift's papers, with the extensive descriptions of the star fields, in hand when he was scanning the ESO B-band plates. Andris, of course, had other things in mind when he did the ESO-B survey.― IC Notes by Harold Corwin
