The National Large Solar Telescope (NLST) is a Gregorian multi-purpose open telescope^[1] proposed to be built in Merak village in Ladakh in India and aims to study the sun's microscopic structure.^[2]

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.^[3]

Location

The proposed site for the location of the telescope is Merak village in Ladakh, India. The village is near Pangong Lake.^[3]

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.^[1] 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.^[4]
