Hi Al
What I find puzzling is the lack of a linear x2 multiplication factor between the top (x5) image and the bottom (x2.5) image. These were taken using the same, simple configuration. That is the ToUcam was plugged directly into the x2.5 and the x5 and then the Powermates were just plugged straight into the focuser in turn? Both bottomed out in the focuser, and the ToUcam bottomed out in both Powermates.
It looks like the x2.5 is behaving closer to a x2.2 system?
Cheers
Dennis
