Abstract

At Kitt Peak National Observatory a, active control of the f/8 secondary mirror on the Mayall, 4m telescope, was installed as phase two of a three phase project improving the telescope's delivered image quality. The resulting changes provide 400 times the previous resolution of control to the existing secondary mirror and its support cell. The redesign and method used to give 100 nanometer control of the secondary's tip, tilt and focus is presented in this paper.
