NGC/IC Project Restoration Effort

===== NGC 6811. JH has two observations of this, separated by nearly a minute of time in RA and 6 arcmin in Dec. The RA of the first observation is correct, while the declination of the second is correct. Unfortunately, the position JH adopted for the GC carries the RA of the second, and a declination ten arcminutes further on north. I think he meant to use only the second observation (he notes that the first observation refers to "A double star in the southern part ..."), so the incorrect RA must be a transcription or typographical error. Once these errors are corrected, though, N6811 turns out to be quite a nice cluster, ten or twelve arcmin across, with perhaps a hundred stars, many of the 10th and 11th magnitudes.

===== NGC 6811 17.5" (7/1/00): large, beautiful cluster at 100x. The central section is ~8' in diameter, roughly triangular and contains a scattering of ~20 10-11th magnitude stars. There are no prominent members - the brightest star (at the west edge) has a faint companion. Perhaps 85 stars are resolved in the unconcentrated central region (there is nearly a void in the center) over haze. The richest knot of stars is on the northeast side. An isolated 5' tails of stars extends NW and another curving string of stars can be traced 8' to the east. 13" (9/3/83): fairly large and rich group of approximately 60 stars including many mag 11-12 stars. A long trail of stars follows and a bright group of stars is WNW. Prominent in 16x80 finder, some resolution with averted.
