5 August 2010 VISTA M1 support system
Author Affiliations +
The VISTA Telescope1 is obtaining superb survey images. The M1 support system is essential to image quality and uses astatic pneumatic supports to balance the M1 against the varying effects of gravity and wind, with four axes being actively controlled via software and CANbus. The system also applies externally determined active optics force patterns. The mechanical, electronic, software and control design and as-built operation of the system are described, with the practical design points discussed.
