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[edit]

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

Telescope[edit]

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]
