Steve's Notes

===== NGC 7558 24" (12/28/13): faint to fairly faint, small, elongated 4:3 ~N-S, 16"x12", low even surface brightness. The redshift of this galaxy is over ~70% greater than the other four members of HCG 93, so it is probably a background object. 24" (12/1/13): faint to fairly faint, small, round, 20" diameter, weak concentration. Nearly collinear with two mag 14.5 stars [22" separation] located ~2.8' S. 18" (8/25/06): very faint, very small, round, 20" diameter. Collinear with two mag 14.5-15 stars. Furthest east of five members viewed in HCG 93. 18" (9/3/05): extremely faint, very small, round. Can hold steadily with averted vision. A close, faint pair of mag 14.5-15 stars (separation 22") lies 2.6' south. 18" (8/27/05): extremely faint, extremely small, round. Collinear with a pair of faint stars to the south that help in pinpointing the location. 17.5" (9/7/96): extremely faint, very small, round, 20" diameter. Collinear with a pair of mag 14.5 stars oriented N-S that lie 2.5' S. This galaxy and HCG 93D = CGCG 454-015 = NGC 7553? (NGC identification uncertain) are the two faintest members of the HCG 93 quintet. Located 6' SE of NGC 7550 = HCG 93A. 17.5" (9/23/89): extremely faint, very small, round. An easy pair of mag 14.5 stars with separation 22" oriented N-S lies 2.5' S. Located 5.8' ESE of NGC 7550 in HCG 93 and faintest of four viewed.
