I really need some help here A-mart'ers. I just purchased a Skywatcher 150mm refractor to placate me until AP130 arrives. I purchase this from a so-called reputable Canadian dealer who supposedly tests all his scopes prior to shipment. I have tried numerous times in the last 2 weeks to perform and interpret a star test. While I get nice round evenly spaced rings inside of focus, outside of focus all I get is a big fuzz ball. I have tried this numerous times and get the same results. I am using a nagler 3-6 zoom at 240X to 300X and no diagonal. I am defocusing to 6 rings. Should I interpret this as really bad undercorrection or is there another explanation? I am getting really pissed off and starting to think I got hosed. The dealer insists he tests all his scopes and that is the seeing. I fail to see how I can get such tight crisp rings on one side of focus and a light explosion on the other.
