Steve's Notes

===== NGC 190 48" (10/25/11): HCG 5A is the brighter northern component of a double system forming NGC 190. It appeared bright, moderately large, slightly elongated E-W, 50"x40", bright core, stellar nucleus. Forms a very close double with smaller and fainter HCG 5B just 21" between centers. The halos of the two galaxies are in contact. HCG 5C is 0.8' NNE and HCG 5D is 0.9' S. The entire length of the N-S chain of four galaxies is 1.6'. 18" (8/26/06): this double system was just resolved into two very close, small knots, roughly 20" each in diameter with their halos in contact. Both components have faint stellar nuclei. The northern component (HCG 5A) was slightly brighter and larger. HCG 5C is a difficult object 1' NW. The entire quartet is arranged in a N-S chain with a total length of only 1.6'. 18" (11/23/05): NGC 190 is a double system which often appears as an elongated glow, 40"x20", oriented N-S. With careful viewing, the system just resolves into two very small round knots, just 20" between centers. The northern component is ~20" diameter and the southern member ~15". The two knots both have faint stellar nuclei and appear virtually tangent. A third member, HCG 5C, is occasionally visible as an extremely faint knot off the NW side. 17.5" (12/11/99): Initially seen as a single faint, elongated glow at 220x. At 280x in moments of good seeing this object cleanly resolved into two very close, very small knots with the brighter component on the north side. HCG 5C was only intermittently visible with averted vision as a 15" threshold knot. 17.5" (9/5/99): NGC 190 is a challenging double system best viewed at high power. Using 280x, at first appeared as an elongated irregular glow but with extended viewing, two "knots" oriented N-S were resolved within a common halo. The brighter and larger component (HCG 5A) is at the north end and appears very faint, very small, round, 20" diameter. The southern component (HCG 5B) is extremely faint and small, perhaps 15" diameter. HCG 5C is a threshold knot 1' NW. The HCG is a subgroup of AGC 76 whose core is ~20' SSE and includes IC 1565, 1566 and 1568. 17.5" (10/8/88): very close double system, faint, small, elongated SSW-NNE, irregular. HCG 5B is a very small companion attached at the south edge just 22" between centers. In a compact group of four (HCG 5).
