split NGC 7318 (Halifax)

I was interested in viewing NGC 7318 A and B. They are members of Stephan's Quintet. I had not had a really good view so I ordered the Burke-Gaffney Observatory to centre on NGC 7320 in Pegasus. A wonderful region with many faint galaxies. The image shows elongated stars and a satellite but I don't care. It was good to dive deep into this cluster.

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, GIMP. North is up; east is left.

NGC 7319, a canted oval, is to the north-east. 7318 A and B are horizontally arranged, east through west. A is to the right or west. B looks like a barred spiral with long curved arms. NGC 7317 is south-west, a round fuzzy very near a star, GSC 02743-1548. And NGC 7320 is a large spiral lacking a bright core.

To the south-south-east I see an oval shape, a galaxy. SkyTools 3 Pro does not show a galaxy; rather a star, J223632.1+334746, is noted.

Far away, due east, is a small fuzzy oval, lying under the satellite trace: LEDA 141041.

NGC 7320C is to the east-north-east.
