Integrated adaptive optics system for small telescopes

摘要

We describe a compact integrated module implementing a low-cost adaptive optics system. It is targeted as acorrection systen for small telescopes with primary mirror diameter up to 1 m, operating on a natural guide starwith magnitude at least 4 (for a 25 cm telescope). It is supposed to provide stable diffraction-limited imagingof stars, double stars, planets and artificial bodies in various seeing conditions. Besides, it allows correcting forstatic aberrations of the telescope, observer's ocular aberrations and fine adjustment of focus. The first on-skytests have demonstrated closed-loop operation with correction for aberrations
