Well, thanks for the inspiration to re-calibrate my setup Peter. I have done PEC and a new mapping run now. It hasn't changed much but has slightly improved my tracking accuracy. So .....

Unguided 600s exposures:
1 : Meade 12" prime focus
2 : Megrez 90 piggybacked

being unguided, there must be a whole bunch of movement somewhere in the megrez!!! it just keeps on drifting. Amazing. Going to have to hunt it down.
