Steve's Notes
=====
NGC 6819
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. Located 8.5' SE of mag 6.3 HD 186307.
13" (8/24/84): 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.
13.1" (9/11/82): striking cluster at 144x. Nearly three dozen stars are resolved over haze mainly in two rows. This is a very rich, dense group.
8": rich, well-resolved, pretty.
