Steve's Notes

===== NGC 5829 18" (8/4/05): the brightest member in HCG 73 appeared faint, small, slightly elongated 4:3, ~0.6'x0.45', low surface brightness with very little concentration. Located 1.2' E of a mag 12 star and a mag 14 star lies a similar distance east. Forms a close pair with IC 4526 = HCG 73B 1.3' NW. IC 4526 appeared extremely faint and small, round, 10" diameter. Forms the northern vertex of an equilateral triangle with sides of 1' with NGC 5829 and a mag 12 star. Once this difficult galaxy was noticed, it was visible most of the time using averted vision and concentration at 225x. The pair forms Arp 42 ("spiral with LSB companion on arm"). The redshift of NGC 5829, though, is less than half that of HCG 73B, C and D, so is a foreground object. 17.5" (7/8/94): fairly faint, slightly elongated 4:3 E-W, 1.2'x0.9', very weak concentration, irregular or mottled surface brightness. Located between a mag 11.5 star just off the west edge 1.2' from center and a mag 13.5 star 1.3' ESE of center. This is the brightest member of HCG 73.
