Adaptive Optics - Orion's SteadyStar
Has anyone used one of these yet? They're fairly expensive and the prism inside seems to be darned small and able to be tilted only and not moved in any other axes (unlike some other AOG devices). That could make it quite a challenge to find a guidestar at longer FLs.
I'd be interested to hear what others thought of this, say the other obvious contenders.
