Steve's Notes
=====
NGC 5821
18" (5/3/08): This is the fainter northeast galaxy forming Arp 136. At 280x it appeared faint, moderately large, elongated ~2:1 NW-SE, 1.1'x0.6', low even surface brightness. Located 3.7' NE of NGC 5820 and 6' NW a wide bright pair of mag 7 stars. It helped to keep this bright pair outside the field.
17.5" (5/23/87): very faint, diffuse, elongated NW-SE. Two bright stars ADS 9474 = 6.8/7.4 at 40" located 6' SE interfere with viewing. Located 3.7' NE of brighter NGC 5820.
