Observing Notes
Harold Corwin
IC 1325 = NGC 6928 and IC 1326 = NGC 6930. Swift's RA's are correct, but he has his declinations reversed. He apparently changed his descriptions to match his positions, because the fainter of the two objects is in fact south- east of the brighter.
Howe was the first to suggest the correct identifications with Marth's NGC objects. Reinmuth, however, made IC 1325 = NGC 6927 and IC 1326 = NGC 6928. These mistaken identities were copied by Carlson, and are sometimes still quoted today. Swift's detailed notes about the stars neighboring N6930 clearly identify it, though, and his RA of NGC 6928 does the same for the brightest object in the group. Howe correctly notes that Swift saw the two brightest in the group, and Reinmuth is just as clearly wrong.
