• Source: Siding Spring 2.3 m Telescope

The 2.3 metre telescope at Siding Spring Observatory is operated by the Australian National University. The Advanced Technology Telescope was constructed during the early 1980s and featured, at the time, bold features and design: an unusually thin mirror, an alt-az mount and co-rotating dome. The optical telescope has Altazimuth mount and a primary mirror with a focal length of f/2.05. It is housed in a box-shaped building which rotates as the telescope tracks objects.
Instrumentation includes an integral field spectrograph known as WiFeS, an echelle spectrograph, and a Nasmyth imager. The telescope is a workhorse for numerous large programs where it is used to do follow-up observations on objects of interest before more extensive observations are made at larger telescopes. It is also a valuable tool for training students in the astronomical observing techniques.




History


The telescope was the initiative of Don Mathewson. It was inaugurated Prime Minister, Bob Hawke on 16 May 1984. It was regarded as an achievement in high technology for Australia. In 1985, it won an award from the Institution of Engineers.
In 2023 the telescope was automated to robotically study astrophysical explosions




Mirror


The mirror used in the telescope is much thinner than those typically used in a telescope mirror. Its ratio of diameter to thickness is about 20:1. The light mirror and rotating design allows the telescope to be rapidly moved as observations are made.
