From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 1545 NGC 1545 = Cr 49 = OCL-399 = Lund 131 04 20 56 +50 15.3 V = 6.2; Size 18 17.5": about 50 stars scattered evenly over a 20' field with no dense areas or central concentration. A pretty pair of mag 7/8 stars are near the center (S445 = 7.3/8.2 at 72") with a blue mag 9 star to the W (SAO 24549) forming an isosceles triangle. A number of mag 11/12 stars are arranged in a curving stream oriented SW-NE which passes through the bright pair. At the N end is a pretty colored pair ?519 = 7.9/9.4 at 18". Off the E side is a small circular group of five faint stars and one brighter star in a clump. 8": about two dozen stars in the cluster. The three brightest stars are mag 7.5-8.5. Includes chains of faint stars with double star ?519 = 7.9/9.4 at 18" at the N edge. - by Steve Gottlieb |
