Description:
At 40x, this OC is smaller than NGC 7789 and gives the appearance of compact
salt&pepper look with a prominent 8th magnitude orange star, SAO 20606. Better
view at 30x and is roughly compact, oval. Start to resolve the stars at 60x
with some 10 bright stars. 110x brings the stars out and are clearly seen.
The OC lost its compactness.
