Nice camera. I've long wanted to upgrade my ST7 to an ST8 or ST10.
I've found using focus masks in CCDSoft hasn't worked well for me, not quite sure why. Might be similarly tricky in CCDOps for whatever reason. I've only tried in CCDSoft with my DSLR, not ST7.
10 mins is pretty long for Eta, F/2.8 (or even slightly slower) & an ST8! I'm surprised it's not burnt out more than it is
