NGC 6764
24" (6/29/16): at 260x; moderately bright, very elongated 5:1 WSW-ENE (central bar), ~1.7'x 0.35', broad weak concentration, sharp stellar nucleus. After careful viewing, a very low surface brightness halo surrounds the bar and increases the size to ~1.7'x0.6'. Three mag 14-15 stars are at the south side including a 10" pair parallel to the major axis [25" south of the nucleus]. A faint non-stellar knot was visible at the ENE end of the bar. Occasionally it was elongated and angled towards the north. A matching knot was suspected (lower contrast) at the WSW end of the bar.
Forms a pair with LEDA 214715 2.7' ESE. At 260x, the companion appeared faint to fairly faint, small, slightly elongated E-W, 20"x16" or perhaps 15"x12", weak concentration, slightly brighter nucleus. Visible continuously at this magnification.
13.1" (10/20/84): fairly faint, diffuse, fairly small, slightly elongated WSW-ENE, very diffuse edges. Two or three faint stars are superimposed on the halo south of center although one of these may be a faint stellar nucleus. A nice double star is 6' WNW (mag 11/12 at 20"). Located on the Cygnus-Draco border.
