NGC 6721
30" (11/6/10 - Coonabarabran, 264x): fairly bright, moderately large, elongated 4:3 NW-SE, sharply concentrated with a very small bright core increasing to a bright, stellar nucleus, halo appears as an irregularly shaped oval. IC 4806 lies 14' NNE. Located 28' NW of mag 6.3 HD 176522 and 15' NNE of mag 7.6 HD 175675. The latter star, NGC 6721 and IC 4806 are collinear with NGC 6721 at the midpoint.
IC 4806 appeared fairly faint, fairly small, very elongated 4:1 SSW-NNE, 0.8'x0.2', sharply concentrated with a very small, bright core and stellar nucleus. A brighter star is superimposed on the SE edge and a very faint star is at the NNE tip. Located 14' NNE of the large spiral NGC 6721 and 6' SE of mag 9.5 HD 176085.
