Steve's Notes

===== NGC 7317 18" (6/25/04): faint, very small, round, ~20" diameter. A mag 13 star just off the NW side detracts from viewing. This star is collinear with two mag 13.5 stars 0.7' NE and 1.7' SE with a mag 14.5 star just off this line. These and a few additional faint stars near or attached to galaxies in the group (NGC 7320) contribute to the challenge and fascination of these five galaxies. 17.5" (9/14/85): fourth brightest of five in Stephan's quintet. Fairly faint, small, round, brighter core, easy with direct vision. A mag 13 star is at the NW edge just 16" from the center which confuses the observation. The interacting pair NGC 7318A and NGC 7318B is 1.6' NE and NGC 7320 is 2.5' E. 13.1" (9/29/84): very faint, small, round. A star is at the NW edge. Second faintest in Stephan's quintet. 13.1" (8/23/84): very faint, small, round, visible without averted vision. 13.1" (8/5/83): extremely faint, very small, round, close following a star, requires averted vision.
