Steve's Notes

===== NGC 7172 24" (8/23/14): moderately bright, fairly large, elongated 5:2 WNW-ESE, ~1.5'x0.6', increases in size with averted. Contains a brighter, elongated core that bulges slightly and the halo has a sharper edge along with south edge. NGC 7173, 7174 and 7176 triplet lies ~7' SSE, the quartet forming HCG 90. 18" (10/21/06): moderately bright, fairly large, elongated ~2:1 E-W, ~1.8'x1.0', broad concentration. A mag 10.6 star lies 2.5' SE and two mag 13 stars 1.5' SW and 3' SW are collinear with the galaxy. 18" (9/3/05): moderately bright, fairly large, elongated 5:2 WNW-ESE, 1.4'x0.6', contains a brighter bulging core. A mag 10.5 star lies 2.5' SE. Located ~7' N of the main grouping (NGC 7173, NGC 7174, NGC 7176) in HCG 90) and largest in the group. 13.1" (7/27/84): moderately bright, fairly large, elongated, fairly diffuse. Brightest of four in HCG 90. The compact trio consisting of NGC 7173, NGC 7174, NGC 7176 is roughly 7' S. 8" (7/24/82): very faint, fairly small, elongated E-W.
