Abstract

The Arcetri Adaptive Optics group is in charge to design and build a closed loop control system for the reduction of astronomical image motion to be used in the Italian 3.6 meters “Telescopio Nazionale Galileo” (TNG) [4]. After the realization of an analog system prototype [1] the Arcetri Adaptive Optics Group has carried on the project of the final version of the control system that is scheduled to be ready for the telescope first light in middle ’96. The tip-tilt system is the first step in the implementation of a fully developed system which will also correct higher order terms.
