Steve's Notes

===== NGC 7102 24" (7/30/16): fairly faint, moderately large, roundish, fairly low overall surface brightness, broad weak concentration. On images NGC 7102 appears to be interacting with PGC 214783, an edge-on 1.1' SSW. At 220x, it was glimpsed several times in the same position. It was too faint for any details, including elongation, but appeared very small. 24" (8/23/14): fairly faint, fairly large but diffuse, elongated 3:2 or 4:3 NNW-SSE, ~1.3'x0.9' but halo appears to alter its shape with averted vision (sometimes smaller) as fainter parts of the halo pop in and out of view. A mag 10.2 star lies 3.5' SSE. PGC 214783, an extremely faint edge-on, is just 1' SW. With careful viewing I had 2 or 3 momentary "pops" at this position over a couple of minutes, too fleeting for any details. 17.5" (8/2/86): moderately large but very diffuse, gradually brightens in the middle, slightly elongated NW-SE. A mag 10 star is 3.5' SSE.
