The 3.6-meter optical telescope contains a reflecting mirror weighing 4.3 tonnes and operates with an active optics system at 2,540 meters elevation.
Indian Prime Minister Narendra Modi and Belgian Prime Minister Charles Michel remotely activated this telescope from Brussels on March 31, 2016.
The telescope represents a major advancement in Indian astronomy, enabling scientists to conduct detailed observations of celestial objects at optical wavelengths.
The telescope features three Cassegrain ports with an optical spectrograph, a CCD imager, and a near-infrared spectrograph for varied astronomical research.
This facility stands as the largest reflecting telescope in Asia, filling a substantial gap in the distribution of 4-meter class telescopes across the continent.
