VISTA M1 support system

Brian Stobie, Paul Jeffers, Malcolm Stewart, Andy Foster, Juan Delgadillo, Larry M. Stepp, Roberto Gilmozzi, Helen J. Hall
2010 Ground-based and Airborne Telescopes III  
The VISTA Telescope 1 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.
