This telescope was built in England in 1961 and extensively modified after its delivery to Victoria.
As with the Plaskett telescope, the 1.2-m telescope is used every clear night of the year, which is about 200 nights per year.
The 1.2-m telescope is 4 metres in length and has a fixed focus on the main floor of the building, beneath the telescope, a so-called coudé focus. Light passes to this focus by a series of mirrors through the telescope mounting, which is hollow. The telescope is equipped for spectroscopy only and can be used in fully robotic mode.
The 1.2-m telescope is primarily used for studies of binary star systems in order to determine basic information about stars such their masses, motions, and chemical compositions. Due to its proximity to NRC-HIA headquarters, the telescope is also often used as a test bed for various instrumentation development projects.
The telescope is closed to the public.
