Abstract : ARIES is well known for its astronomical sites at Devasthal and Manora Peak in Nainital. It has set up various telescopes at its sites for observations of celestial objects to carry out stellar and solar research activities. Devasthal site with sub-arcsecond seeing capability has got India’s largest 3.6m optical telescope, 1.3m Devasthal fast optical telescope and 4m International liquid mirror telescope. 1.04 m Sampurnanand telescope, 0.5m Baker-Nunn Schmidt telescope and 0.15m Solar telescope are installed at Manora Peak site. Various types of enclosures such as cylindrical dome, hemispherical steel dome and motorized roll-off roof etc. were built for meeting operational requirements of different telescopes at sites to support scientific observations. With advancements in telescopes at ARIES, selection of appropriate size and structural materials of these enclosures has provided compactness and low thermal mass along with environmental protection to maintain their image quality. Present article reviews different types of telescope enclosures in operation at ARIES and advancements in their technologies for meeting telescope demands.
