| Notes: | This field contains two objects that are not plotted on my charting software
(Megastar v5.0.12). The plume of nebulosity just above NGC 225 is the
Bright Nebula vdB 4 (GN 00.40.4), and just above vdB 4 is the
southern end of the Dark Nebula LDN 1302. From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 225NGC 0225 = Cr 7 = OCL-305 = Lund 25 00 43.5 +61 47 V = 7.0; Size 12 17.5": about two dozen stars at 100x in a 12' diameter. Bright but scattered. Outline forms an isosceles triangle with the vertex at W edge and the long base on the E side. Most stars are mag 10-11 and evenly spaced. The cluster appears completely resolved. Only one fairly close double star in group. Just ENE of the main group is a line of five mag 9 stars oriented N-S. 8": two dozen stars in cluster, fairly bright but scattered, no dense spots. - by Steve Gottlieb |
