The Center for Research and Education in Science and Technology (CREST) is situated 35 km to the northeast of Bangalore near Hoskote town. Center for Research and Education in Science and Technology The telescopes are deployed on the periphery of a circle of radius 50 meters with one telescope at the center. Each telescope has 7 mirrors with a total area of 4.4 square meters. The High Altitude Gamma Ray Telescope (HAGAR) is an atmospheric Cerenkov experiment with 7 telescopes setup in 2008. The telescope is operated jointly by IIT Bombay and the Indian Institute of Astrophysics. It was set up as a part of the international GROWTH program, and has been widely used for time domain astronomy. It is the country's first fully robotic research telescope. The GROWTH-India telescope is a 0.7 meter wide-field optical telescope that had first light in 2018. High Energy Gamma Ray Telescope (HAGAR), Hanle GROWTH-India Telescope The telescope is remotely operated via an INSAT-3B satellite link which allows operation even in sub-zero temperatures in winter. The telescope is mounted with 3 science instruments called Himalaya Faint Object Spectrograph (HFOSC), the near-IR imager and the optical CCD imager. The telescope was manufactured by Electo-Optical System Technologies Inc.
It contains a modified Ritchey-Chretien system with a primary mirror made of ULE ceramic which is designed to withstand low temperatures it experiences. The Himalayan Chandra Telescope is a 2.01 meters (6.5 feet) diameter optical-infrared telescope named after India-born Nobel laureate Subrahmanyam Chandrasekhar.
The HCT is remotely operated from Bangalore from the Centre for Research and Education in Science and Technology (CREST) using a dedicated satellite link. These are the 2.01 meter optical-infrared Himalayan Chandra Telescope (HCT) and a High Altitude Gamma Ray Telescope (HAGAR).
The Observatory has two active telescopes. In addition, there are low ambient temperatures, low humidity, low concentration of atmospheric aerosols, low atmospheric water vapour, dark nights and low pollution.

Specifically the observation conditions yield about 255 spectroscopic nights per year, approximately 190 photometric nights per year and an annual rain plus snow precipitation of less than 10 cm. The Hanle site is deemed to be excellent for visible, infrared and submillimeter observations throughout the year. The Observatory was dedicated to the nation on 29 August 2001. The satellite link between the Centre for Research and Education in Science and Technology (CREST), Bangalore and Hanle was inaugurated by the then Jammu and Kashmir Chief Minister Dr. The first light was seen by the Observatory 2-metre telescope on the midnight hour between 26 September and 27 September 2000. The scientists from the Indian Institute of Astrophysics found the site at Hanle.
The search for the site of the observatory was taken up in 1992 under the leadership of Prof. Sreekantan recommended that a national large optical telescope be taken up as a priority project. In the late 1980s a committee chaired by Prof. Accessing the observatory, located near the Chinese border, requires a ten-hour drive from Leh Ladakh, the district capital of Leh.
