Steve's Notes

===== NGC 6161 24" (7/15/15): at 375x; fairly faint, small, elongated nearly 2:1 N-S, 24"x12", very small bright nucleus. A mag 16 star is at the south tip. 24" (6/16/12): at 322x this member of HCG 82 appeared faint to fairly faint, small, elongated 2:1 N-S, 0.4'x0.2,' very small brighter nucleus. 18" (6/7/08): this is the third brightest member of the HCG 82 quarter. At 260x it appeared very faint, small, elongated ~5:2 N-S, 33"x12". Located 2.3' S of NGC 6162. HCG 82D, the faintest member, lies 50" WNW. 18" (8/3/05): the third brightest member of HCG 82 appeared very faint, very small, slightly elongated N-S, just 0.3'x0.2'. Forms the southwest vertex of a small right triangle with NGC 6162 2.2' N and NGC 6163. The difficult 4th member, PGC 58231 is just 48" west. 17.5" (8/14/96): the third brightest member of HCG 82 appears very faint, very small, elongated 2:1 ~N-S, slightly brighter core. In a compact quartet with HCG 82D 50" WNW and NGC 6162 = HCG 82A 2.3' due north. 17.5" (7/1/89): very faint, very small, low even surface brightness. In a tight trio (HCG 82 group) with NGC 6162 2.3' N and NGC 6163 2.6' NNE. Located 10' NE of mag 7 SAO 65320.
