Abstract

The telescope enclosure for the Sloan Digital Sky Survey 2.5 meter telescope is the first roll-off design used on a telescope of this size. The roll-off design eliminates dome-induced image degradation because the telescope enclosure is rolled downwind of the telescope during observations. Flow visualization techniques were used to study a 1/72 scale model of the enclosure in a water tunnel.
