Performance of the Multiple Mirror Telescope (MMT). VI - MMT telescope coalignment system
Abstract
The alignment of the Multiple Mirror Telescope (MMT) objectives so that the different star images coincide to within a fraction of the image size is conducted by the Telescope Coalignment System (TCS). The TCS is an autoguider which simultaneously operates on six telescopes, automatically coaligning them and tracking a field star. When such a star is not present in the small 4-arcmin field of view, the TCS coaligns the MMT on a nearby star and then tracks and maintains alignment of the six telescopes under computerized control, using separate flexure corrections for each.
