Sites in the Himalayan region at altitudes greater than 4 000 m that have extremely low water vapor content and are unaffected by monsoons are under evaluation. This project is led by the Indian Institute of Astrophysics and has national and international partners. Its geographical location will fill the longitudinal gap between Japan and Europe and is expected to be the largest solar telescope with an aperture larger than m till the 4 m class Advanced Technology Solar Telescope ATST and the European Solar Telescope EST come into operation. NLST is an on-axis alt-azimuth Gregorian multi-purpose open telescope with the provision of carrying out night time stellar observations using a spectrograph at the Nasmyth focus. The telescope utilizes an innovative design with low number of reflections to achieve a high throughput and low polarization. High order adaptive optics is integrated into the design that works with a modest Fried s parameter of 7 cm to give diffraction limited performance. The telescope will be equipped with a suite of post-focus instruments including a high-resolution spectrograph and a polarimeter. A small 20 cm auxiliary telescope will provide full disk images. The detailed concept design of the telescope is presently being finalized. First light is expected in 2013. Space Coronagraph A visible emission line coronagraph that uses an innovative design to simultaneously obtain .
