Thanks ving and Larryp
ving: I never could have done this without guiding. About 2.5s without tracking for 200mm. I was able to do 120s with the AstroTrac without accurate setup!
I didn't accurately line up celestial south because there were trees in the way. Used a dodgy compass and set up the incline for my latitude. I tried 8 min exposures, and the stars trailed and therefore unusable, so I found my limits for the night.
The setup worked great, but sensitive to vibration - even touching the remote timer. Lucky there wasn't to much breeze
