Corwin's Notes

===== NGC 7653 is not IC 1488, which see.

Steve's Notes

===== NGC 7653 24" (9/29/16): at 375x; moderately to fairly bright, moderately large, slightly elongated ~N-S, 1.0'x0.8', bright core, very small well-defined nucleus. Brightest in a group of galaxies with LEDA 214955 3.2' NNE. This dim galaxy was extremely faint and small, ~6"-8" diameter, only visible occasionally. LEDA 165923, 6.3' ESE, was very faint to faint, small, slightly elongated NNW-SSE, ~15"x11". UGC 12590, 7' SE, appeared fairly faint, fairly small, very elongated 7:2 NNW-SSE, contains a sharp stellar nucleus and faint thin extensions. IC 1488, 12.8' ENE, was faint to fairly faint, fairly small, very elongated 3:1 or 7:2 ~N-S, ~30"x9", contains a very small or stellar nucleus. Only UGC 12590 has the same redshift as NGC 7653. The other mentioned galaxies lie 3 times the distance (~570 million l.y.) and are probably outlying members of Abell Galaxy Cluster 2593, which lies ~35'-40' S. 24" (1/1/16): at 375x; fairly faint or moderately bright, fairly small, slightly elongated N-S, 0.6'x0.5', small bright core. LEDA 214955 is a challenging target 3.2' NNE. It appeared extremely faint (V = 15.6) and small, round, 6" diameter, only visible intermittently. 17.5" (7/28/92): fairly faint, fairly small, round, broad concentration to a small bright core.
