Steve's Notes

===== NGC 7103 18" (8/9/10): brightest of 10 galaxies viewed in cluster ACO S963 with IC 5122 4' NNW, NGC 7104 4' NE and IC 1393 6.5' NE. At 225x appeared fairly faint, fairly small, irregularly round, 40"x35", weak concentration with no core or zones. A mag 13.7 star lies 2' ENE. The distance of the cluster is ~440 million l.y. 18" (8/12/07): largest and brightest of 6 members viewed in galaxy cluster ACO S963. At 260x appeared fairly faint, fairly small, slightly elongated, ~30"x25", broad weak concentration. Occasionally I glimpsed a nearly stellar galaxy (2MASX J21394761-2228171) just 0.9' W. Located 45' NNW of gc M30. 17.5" (10/13/90): faint, small, round, small bright core, stellar nucleus. Brightest in cluster ACO S963 with NGC 7104 4.0' NE, IC 5122 4.2' NNW, and IC 1393 6.4' NE. Globular cluster M30 lies 45' SSE.
