Abstract

AMOS SA has been awarded of the contract for the design, manufacturing, assembly, tests and on site installation (Devasthal, Nainital in central Himalayan region) of the 3.6 m Indo-Belgian Devasthal Optical Telescope (IDOT). The telescope has Ritchey-Chrétien optical configuration with one axial and two side Cassegrain ports. The meniscus primary mirror is active and it is supported by pneumatic actuators. The azimuth axis system is equipped with hydrostatic bearing. After successful factory acceptance at AMOS SA, the telescope has been dismounted, packed, transported, and remounted on site. This paper provides the final performances (i.e. image quality, pointing and tracking) measured during sky tests at Devasthal Observatory.
