The Sundai senior high school built a telescope with an alt-az mounting and an aperture of 75cm. A photographic camera at the prime focus, and an SIT camera, a photomultiplier, and a spectrograph at the Nasmyth focus are prepared. Time needed for the exchange between instruments is in less than a minute. Therefore, effective observations are performed by changing the instruments which are proper for the sky condition at the observed night.
