The Indian Institute of Astrophysics is the nodal agency charged with various scientific bodies like the Indian Space Research Organisation (ISRO), Aryabhatta Research Institute of Observational-Sciences, Tata Institute of Fundamental Research (TIFR) and Inter-University Centre for Astronomy and Astrophysics (IUCAA) also participating.{{cite web|author=IANS |url=http://www.deccanchronicle.com/national/india-build-worlds-largest-solar-telescope-999 |archive-url=https://web.archive.org/web/20100903074607/http://www.deccanchronicle.com/national/india-build-worlds-largest-solar-telescope-999 |url-status=dead |archive-date=3 September 2010 |title=India to build world's largest solar telescope |publisher=Deccan Chronicle |date=2010-09-02 |accessdate=2010-12-23}}
Location
The proposed site for the location of the telescope is Merak village in Ladakh, India. The village is near Pangong Lake.
Telescope
NLST is proposed to be on-axis alt-azimuth Gregorian multi-purpose open telescope with the provision of carrying out night time stellar observations using a spectrograph. It hopes to resolve features on the Sun of the size of about 0.1 arcsec. The focal plane instruments are to include a high-resolution polarimeteric package to measure polarization with an accuracy of 0.01 per cent, a high-spectral-resolution spectrograph to obtain spectra in 5 widely separated absorption lines simultaneously, and high-spatial-resolution narrow-band imagers in various lines.Singh, J.
