High atmosphere solar telescope, a serious gimble/gyro in there somewhere.

"In addition, Sunrise III contains a sophisticated image stabilization system. It ensures that the observatory records highly precise data even on the wobbling balloon. If a target shooter wanted to shoot similarly "wobble-free," he would have to hold his equipment so steady that the shot is deflected by no more than the thickness of a hair over a distance of seven kilometers."

Ps. So, how many hairs in an AU/7km?
