Hi Peter,
Habit I guess. Previously, when I used to image through the 12" lx200, no matter what I tried to guide it with I always seemed to get quite a few unusable exposures. Throwing the adaptive optics into the mix made that problem go away.
I tend to use it even when using the small scope as, it can even cater to slow vibrations from the light wind gusts hitting the scope.
But you are right I should give it another go with just the PEC on the lx and some guiding.
Just need a clear night hehe
