My first image here is of both NGC-1545 and NGC-1528 taken with a 70mm (2-3/4-inch) f/4.8 APO using an SBIG STF-8300C CCD camera. The field of view is approximately 1.5° from left to right. I have circled and labeled the two star clusters. The brightest star in the image is b Persei, a foreground star 318 light-years away.   James Dire
