1 July 1990 Advanced technology in the VATT
Author Affiliations +
The Vatican Advanced Technology Telescope (VATT) now being fabricated differs from traditional telescopes in many ways. The altitude over azimuth mount will be direct driven by large diameter motors. The cell for the f/1 borosilicate honeycomb primary mirror incorporates a thermal control system to stabilize the mirror temperature. The f/9 Gregorian secondary will be mounted on a six-axis stage and controlled to submicron resolution in order to maintain the strict collimation tolerances needed for the fast optical system. Though only 1.83 m in aperture, VATT incorporates many of the design features of larger projects in the 8 m class.
