Do the encoders reduce image shake under windy conditions or while focusing for visual use?
Absolutely, it (near) immediately corrects for shakes due to windy conditions. But why take my word for it when you can hear Roland from Astro-physics explain it and see it demonstratated in this video. Watch from the timestamp included for at least 30 seconds.
Focusing may be a different matter if you have a scope with differential flexure or mirror flop. The mount can't correct for a source of mechanical shift that's beyond it's control.
But the encoders will help to force the mount back into a precise position as a result of being nudged during focusing.
Also, for anyone using plate solving for imaging. Imagine a mount that once properly aligned (sync'ed) going precising to the coordinates and only occassionally needing to do a second plate solve.
That's another nice feature which I was seeing even before I upgraded to absolute encoders. [EDIT] And that's imaging at ~0.5 arcseconds/per pixel with a C9 reduced to F7.
