Abstract

The Iranian National Observatory (INO) 3.4 m optical telescope (INO340), has been installed on Mt Gargash peak at an altitude of 3600 m in central Iran. The optical design of the telescope is Ritchey-Chretien Cassegrain type on an altitude-azimuth mount and offers an unvignetted field of view of 20 arcmin and the focal ratio of f/11.25. It has a total mass of 85 tons with a height of 11 m and a maximum diameter of 7.5 m. The telescope design was optimized to achieve 0.2 arcsec tracking accuracy and 3 arcsec blind pointing accuracy. The finite element analyses have been carried out during the design phase to make sure of the functionality and safety of the telescope. This paper presents the mechanical design, analysis and manufacturing of the telescope.
