Three modern optical telescopes of sizes 1.3-m, 3.6-m, and 4-m are installed at Devasthal, Nainital, located in the central Himalayan region of Kumaun, Uttarakhand. The 3.6-m Devasthal optical telescope is designed to be a technologically advanced and complex astronomy instrument. All three telescopes are used for night observations of celestial objects. The sky performance of the 3.6-m telescope is not only internationally competitive but also at par with the performance of other similar telescopes located elsewhere in the world. This article provides the global importance of the Devasthal observatory for optical and near-infrared observations in the present era of multi-wavelength astronomical studies.
