Tonight I'm still playing with my new QHY8

- All set up. Slew to ngc3372. Focus is spot on - tracking is good too. I set up 15 x 5 minutes. Check one sub quickly. Bit dark but looks good - not to worry. Set up another run of 15 x 5 minutes. Come back again at the end of the run then realised I've been shooting all along through my cardboard made hartman mask
