Observing Notes

Harold Corwin

NGC 6590 = NGC 6595 = IC 4700. John Herschel found the brightest nebula in this group while observing at Slough; his position is good. Swift came across it and another nearby nebula nearly 60 years later in 1885, but misplaced both by about 45 seconds of time in RA from the correct positions. In a note in AN 3101, Barnard corrected the positions for both of Swift's objects, noting the identity of NGC 6590 with NGC 6595. He also announced the discovery of another larger, though fainter nebula (IC 1284) northeast of the brighter pair. (In still another note in AN 3111, Barnard also announced the discovery of yet another nebula here, IC 1283. See that for more).

Curiously, Barnard mentions the AN 3111 note in AN 4239, but not the AN 3101 note. Had he done so, it might have alerted Dreyer to the identity of one of Barnard's nebulae mentioned there (see NGC 6589 for the passage) with NGC 6595. Had this happened, Dreyer probably would not have been included it in the second IC.

ESO, by the way, notes the cluster associated with the nebula. On the optical DSS images, the cluster appears to be centered about 15 seconds of time to the west. I suspect that the two bright stars near the center of the nebula are also involved with the nebula, so I've adopted the mean of their positions as that for the object.
