Abstract
The Multiple Mirror Telescope is a 150 ton optical instrument composed of an array of six 1.8 m diameter folded Cassegrain telescopes. A mount for the array uses conventional ball bearings and gear trains to permit the telescope to track in two axes, azimuth and altitude. A computer-controlled servo system uses a 26-bit absolute encoder and associated electronics to achieve an all-sky pointing accuracy approaching 1.0 arcsecond RMS, and a tracking accuracy approaching 0.1 arcsecond RMS.
