I have an AO-8 on my that I switch back & forth between my ST2000 / ST10. When I click Calibrate AO, it crates a nice size box on the display screen. The results are that it guide incredible. I was hoping for that with my new one. I have a AO-8A on a SC2 / STC-7. When I calibrate that, it really doesn't hardly move ( see video ). What do I look for, or is this the way the new AO units work? hawkeye-observatory.com/CN/SBIG/AO-8A.avi This is a 27mb file. Thank You Gentlemen.
