Abstract : An H-alpha telescope has been commissioned near the Pongong Tso lake in Merak (Leh/Ladakh) in August 2017. The telescope consists of a 20-cm size refactor controlled by automatic tracker, guider and finder instruments. A Lyot filter centered at 656.2 nm with a pass-band of 0.05 nm and a free spectral range of 5.1 nm, capable of isolating the Balmer line of the hydrogen spectra allows the recording of the solar chromospheric images. In this poster, we report the installation of the telescope, observational data and the preliminary results on the seeing measurements at the site using long exposure images obtained from this telescope.
