Steve's Notes

===== NGC 4111 24" (5/30/16): at 225x; very bright, beautiful edge-on ~7:1 NNW-SSE, 3.5'x0.5'. Sharply concentrated with a small very bright elongated core, with an unusually bright quasi-stellar nucleus. An extremely faint star or stellar knot was suspected near the southeast end. A very wide unequal pair (HJ 2596) with a orange mag 8.1 primary lies 3.7' NE. NGC 4111 is the brightest in a group containing NGC 4109 4.8' SSW, NGC 4117 8.6' NE, NGC 4118 9.4' NE, UGC 7094 11.6' SW and UGC 7089 12.8' NW. All of these galaxies with the exception of UGC 7089 are roughly aligned in a 20' string oriented SW-NE. UGC 7094 appeared very faint, very elongated 4:1 SW-NE, 1.0'x0.25', very low surface brightness with no noticeable concentration. 18" (5/14/07): this striking edge-on is extends 6:1 NNW-SSE, ~3.5'x0.6'. Dominated by a small, sharply concentrated, intense core. The core is only 24"x15" and brightens somewhat to the center. The eastern flank possibly has a sharper edge, but no dust lane was visible. Located 4' SW of a wide double star (8.2/10.7 at 34"). 18" (6/4/05): fairly bright, fairly large, excellent edge-on at least 6:1 NW-SE. Sharply concentrated with a very bright 20" core that increases to the center. The extensions are very thin, ~3'x0.4', with a slightly bulging core. A wide double star (8.2/10.7 at 34") to the northeast is collinear with the core. 17.5": fairly bright, fairly large, edge-on 5:1 NW-SE, small very bright core, long thin extensions. A double star with components mag 8.2/10.7 at 34" separation lies 3.8' NE. Brightest in a group with NGC 4109 4.8' SW and NGC 4117 8.7' WSW. 13" (4/12/86): fairly bright, pretty edge-on, small very bright core, faint thin arms. Located 5' SW of a mag 8 star. In a group with NGC 4109 5' SSW and NGC 4117 8.5' WSW.
