Steve's Notes

===== NGC 7789 17.5" (10/12/85): a few hundred stars were resolved in a 20' field. Remarkably rich and fairly uniform carpet of stars mag 11 and fainter. 8" (11/8/80): extremely rich, uniform in faint stars. Certainly among the top open clusters with this aperture. 15x50mm (9/6/10): bright but unresolved 15' glow. 15x50mm (7/26/06): moderately bright glow, at least 10' diameter. Observed using IS binoculars.
