Bisdee Tier Optical Astronomy Observatory
The Bisdee Tier Optical Astronomy Observatory is an astronomical facility built by the University of Tasmania (UTAS) on Bisdee Tier, Spring Hill, Tasmania. The observatory hosts a 1.27 m optical telescope.
==Telescope==
The telescope has a diameter of . The primary mirror is made from fused silica, thick. The mount for the telescope is equatorial. The telescope design incudes a folded Cassegrain reflector with f/9 and 40 arcminutes of corrected field of view. The image scale on the focal plane is 55 micrometres/arcsec. In addition to its standard Cassegrain focus, the telescope features two Nasmyth focal stations, which allows mounting of additional instrumentation, switched with a remote control.
The telescope, constructed at Mr Harlingten's workshops in Norfolk, Vancouver and Tucson, Arizona, cost 2 million Australian dollars. It was donated to the University of Tasmania by an anonymous businessman.
The telescope will be eventually automated with remote control via microwave link from the University campus allowing control from all over the world by internet.
