Description:
NGC7769; Mag 12.0, Size 2.0' X 2.0', RA 23:51, DEC +20:09
A large, uniform circular halo which gradually brightens to a fairly bright,
diffuse core.  Visible with averted vision at 77x, it was best seen at 193x.
NGC7771 is located ~4' SE.

NGC7770; Mag ~13.0, Size 0.5' X 0.5', RA 23:51.5, DEC +20:06
A small, uniform circular halo which shows no detectable brightening toward
the core.  Visible with averted vision at 128x, it did not bear magnification
well and was best seen at 128x-193x.  NGC7771 is located just off the N. edge.

NGC7771; Mag 12.3, Size 2.0' X 1.0', RA 23:51.5, DEC +20:07
An oval halo elongated NE-SW which, during moments of steady seeing, appears
slightly mottled.  It shows slight, gradual, diffuse brightening toward the
core.  Visible with averted vision at 77x, it was best seen at 193x.  NGC7769
is located ~4' NW and NGC7770 is just off the S. edge.
