Steve's Notes

===== NGC 7609 48" (10/27/16): at 488x; bright, fairly small, roundish, sharply concentrated with an intensely bright nucleus and a slightly elongated halo. NGC 7609 = HCG 95A forms an interacting system with HCG 95D 0.4' SE. HCG 95D appeared fairly faint, small, round, 12"-15" diameter. The beginning of the tidal bridge or loop connecting HCG 95D to NGC 7609 on the north side was faintly visible. MCG +01-59-048 = HCG 95B, situated 1.2' SE, appeared fairly faint to moderately bright, very elongated 7:2 NW-SE, slightly brighter core, ~30" length. Two mag 15 stars are close southwest. MCG +01-59-046 = HCG 95C, 1' SW of NGC 7609, is the faintest in the quartet and appeared as a low even surface brightness sliver, ~30"x6" NW-SE. HCG 95B is likely a a foreground galaxy based on the 2MASS redshift, with the other three forming an interacting triplet. 48" (10/23/11): bright, fairly small, slightly elongated SW-NE, 30"x25" very bright core surrounded by a fainter halo. Forms an interacting pair with HCG 95D (25" between centers) on the southeast side. At 488x the close duo was connected on the north side by a very faint loop or bridge! The tidal plume to the south of 95D (forming a partial ring) was not seen. The total size of the system is ~45"x30", oriented NW-SE. 18" (9/3/05): fairly faint, very small, slightly elongated, 25"x20". Brightest in HCG 95 and forms a double system with 95D. The attached companion (VV 20b = HCG 95D) was extremely faint and small, round, 5" diameter. It was only glimpsed a few times so the observation was not 100% certain. 18" (8/27/05): faint, very small, round, 20" diameter. At times, appeared slightly elongated ~4:3, possibly due to HCG 95D which is attached to the southeast end. Located 3' WNW of a faint, unequal double star. 17.5" (9/7/96): very faint, small, elongated 4:3 WSW-ENE, 40"x30", very little concentration. This is an interacting pair with HCG 95D attached at southeast end (not seen) and HCG 95B lies just 1.2' SE. In the background of the Pegasus I cluster. 17.5" (10/28/89): very faint, very small, stellar nucleus or star superimposed. Located 18' NNE of NGC 7601 in the Pegasus I cluster. On the POSS this is a close double galaxy with stellar nuclei. Brightest in HCG 95. 17.5" (10/12/85): faint, very small, faint stellar nucleus.
