10 meter telescope, 250 Angstrom optics ( 1/20 wave ), ultra thin 5cm thick mirror, or 32 multiple mirrors, compact alta-azimuth mount. Includes new configuration and novel concept for optics supports. which extends the capabilities of the instrument and markedly decreases the cost of fabrication and installation. The completely engineered details include on-site production and finishing of the mirror blank, using the telescope drives and bearings. Design of the foundation and the observatory housing is incorporated in the general arrangement, which also considers "enviornmental" operation of telescope with storage housing. The mirror system and mount structure is particularlly designed to weather the effects of wind and temperature. Extensive use is made of compensating design features, enhanced by computer control. Available foci include prime, Cassegrain, Nasmyth, and coude', with a maximum of four mirrors being required.
