ZWO is gradually developing some high quality astrophotography equipment, but there is one major component it still lacks. That is an adaptive optics device. These originally were manufactured by other companies as a tip/tilt mirror, but this form has been replaced by a tip/tilt prism. The device is used for guiding corrections and works on the principle that a prism suspended magnetically can move much more quickly than a correction sent to a telescope mount; the latter having much greater inertia. So … how about an adaptive optics device as a feature request?
