The adaptive optics system being developed to sharpen images produced by telescopes at Mauna Kea is discussed. An approach based on new components developed and optimized for astronomical applications is described. The approach is limited to low-order wavefront compensation and is used for image stabilization. Avalanche photodiodes were used as sensors and reference stars were employed for sensing wavefront errors in a novel sensing technique based on wavefront curvature measurements. The instrument is described and expected performance is discussed.
