Abstract:
A 3.6-m, f/9 optical telescope is planned to be installed at Devasthal, India (Latitude:29° 21' 40'' N, Longitude: 79°
41' 04'' E, Altitude: 2450 m above msl). The telescope has Cassegrain focus and alt-azimuth mount. The design of
the telescope enclosure and the auxiliary building includes a fixed base enclosure, a telescope pier, a rotating dome
structure, an auxiliary building, ventilation and component handling systems. The design is optimized for thermal,
mechanical, structural, as well as for telescope installation and maintenance requirements. The design aims to
provide seeing limited images within the telescope enclosure. This paper presents design of the 3.6m telescope
enclosure.
