Took some shots of Orion the other day with my Pentax and Astrotracer. ISO 800, 50 sec, F2 with 35mm lens. When I started processing them in the Pentax Digital Camera Utility (DCU5) most of the brighter stars came out looking like golf balls! - not nice sparkly stars at all! I thought I had the focus pretty good, and all the stars were round, but golf balls? Strange....
any suggestions?
