From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 6819 NGC 6819 = Cr 403 = Mel 223 = Lund 900 19 41 18.1 +40 11 12 V = 7.3; Size 5 17.5" (7/1/00): this is a rich, beautiful cluster at 100x. The central 6' contains 80-90 stars over unresolved haze and has an irregular outline with the brighter stars forming a squared off "U" shape open to the north. The cluster extends to ~8' diameter with many faint stars on the SW side. The outline appears elongated SW-NE with the inner bars of the "U" on the NE border delineating a distinct border. 13": over 40 stars resolved at 166x including two intersecting strings. Striking very rich group situated in a rich star field. A mag 10 star is off the SW end and several bright stars are in the field at low power. 8": rich, well-resolved, pretty. - by Steve Gottlieb |
