NGC 1773
30" (11/4/10 - Coonabarabran, 264x): fairly large, bright glow, oval 3:2 ~N-S, 2.2'x1.5'. On first glance, two brighter mag 12/13 stars are offset southwest of the geometric center and separated by 17". But on closer inspection the more central star (0-type supergiant SK -66 43), resolved into a very close double. In additional a couple of fainter mag 15/15.5 stars are superimposed on the north side of the glow. The nebulosity is slightly irregular in surface brightness and brighter along the rim, particularly on the southwest side. This emission nebula is located at the northeast end of the NGC 1763 (Bean Nebula) complex with NGC 1763 centered 9' SW, NGC 1769 7' SSW and NGC 1776 5' SSE.
13.1" (2/17/04 - Costa Rica): this HII region is the furthest NE in a group of HII regions and clusters. Appears fairly faint, fairly small, 1'-1.5' diameter with a couple of stars or a knot near the center. Located 9' ENE of NGC 1763 and a similar distance NNE of NGC 1769.
