> Even so, if the camera can be made stable, then so surely too can a mirror. I don't think it makes sense to look at it as a binary of stable or not stable: the camera can be made stable to a certain degree, and the mirror introduces additional instability (even if just stochastically). I could understand wanting to minimize that.
