Steve's Notes

===== NGC 3995 24" (5/25/14): fairly bright striking galaxy with unusual asymmetric structure, fairly large, elongated roughly 5:2 SSW-NNE, well concentrated with a very bright core containing a short bar oriented E-W. A long linear arm is attached at the west side of the core and extends south ~40". The outer, western edge of this arm has a sharply defined edge and the inner (eastern) side has a low, irregular surface brightness. A short extension (arm) heads northeast from the east side of the core. As a result the core appears offset towards the north, because of the longer southern arm. Mag 6.4 HD 103928 lies 5' ESE and was placed outside the field. 17.5" (2/24/90): moderately bright, moderately large, elongated 5:2 SW-NE, large bright core. Third and largest of an excellent trio with NGC 3994 1.8' SW and NGC 3991 3.8' NW. Located 6.6' W of mag 6.4 SAO 62774.
