It was installed in 1972 by Carl Zeiss, Germany. About the Telescope The telescope is an RC reflector with a Cassegrain focus and mounted on equatorial 2-pier english mount. The 104-cm, f/13 telescope produce a field of around 45 arcmin with corrector at the cassegrain end. The tracking accuracy is around 7 arcsec/hr (0.1 arcsec/min) without guider and is around 0.7 arcsec/hr with guider. Three finder telescopes are also provided with clear aperture of around 10-inch (264 mm, f/14, reflector), 8-inch (200 mm, f/15, refractor) and 4-inch (110 mm, f/7, refractor type).
