Corwin's Notes
=====
NGC 6589 may also be IC 4690 (which see for more discussion). Swift's
position for N6589 is about 36 seconds of time off, a mistake corrected by
Barnard, and included in the IC1 Notes. Ironically, Barnard is also
responsible for a mistake of his own which makes the identity with IC 4690
probable.
Also see the discussion under NGC 6590 and IC 1283 for more on this field.
Steve's Notes
=====
NGC 6589
17.5" (8/18/01): at 100x (unfiltered) this is a bright, roundish glow, ~4' diameter, surrounding a wide pair of mag 10/11.5 stars. On the following side, a small 1' glow seems overlapping, causing the east side to bulge out and extending the diameter to 5'x4'. Forms a prominent pair with NGC 6590 6' SSE in a weakly luminous Milky Way field.
17.5" (6/20/87): at 88x with UHC filter appears as a bright, prominent nebula surrounding a mag 9 star. The nebulosity is more extensive on the following side of the star. Forms a pair with reflection nebula NGC 6595 7' SSE.
13" (7/16/82): very faint, larger than NGC 6590 to the south. Surrounds two stars. IC 1283/1284 lies just NE.
