A prototype of a low cost Adaptive Optics (AO) system has been developed atthe Instituto de Astrofisica de Andalucia (CSIC) and tested at the 2.2mtelescope of the Calar Alto observatory. We present here the status of theproject, which includes the image stabilization system and compensation of highorder wavefront aberrations with a membrane deformable mirror. The imagestabilization system consists of magnet driven tip-tilt mirror. The higherorder compensation system comprises of a Shack-Hartmann sensor, a membranedeformable mirror with 39 actuators and the control computer that allowsoperations up to 420Hz in closed loop mode. We have successfully closed thehigh order AO loop on natural guide stars. An improvement of 4 times in termsof FWHM was achieved. The description and the results obtained on the sky arepresented in this paper.
