Abstract. The F/4 130-cm optical telescope has been installed at Devasthal in October 2010. The Devasthal site at an altitude of ∼2450 m near Nainital has advantages of having best astronomical seeing and dark sky in the country. The first results from the telescope have provided seeing in between 1'' - 1.5'' most of the time. The first results comprising deep observations of galaxies, galaxy clusters, supernova and transients, star forming regions etc. will be presented. The results on the ongoing effort to obtain sub-arcsec seeing using Lucky Imaging method will also be presented.
