Abstract

Since 1999 the National Telescope Galileo (TNG) is offering observative nights to the astronomical community. With the aim of increase the efficiency of the telescope and minimize downtime many changes have been done from the original project. Recently it has been taken the decision to completely renew the electronic hardware and software of the active optics system, essencially based on VMEs and on the obsolete transputers processors. From the optical point of view some important modifications have also been implemented in order to allow the off-axis Shack-Hartmann analisys. Also the CCD cameras and their controllers have been redeveloped and the whole control software has been ported to a new architecture to by-pass the VMEs system and directly interact with the actuators and the CCD controllers.
