20-inch reflector, Edinburgh University, UK, 1967

I can only assume that this is the telescope referred to below....underlined.

The original 1894 building includes two cylindrical copper domes on top of the East and West Towers. These were refurbished in 2010. The East Dome still shelters a 36-inch (0.9 m) Cassegrain reflector that was installed in 1930. This is part of the visitor centre exhibition, but is not operational any more. A 16/24-inch (0.4/0.6 m) Schmidt camera was installed in the West Dome in 1951. In 2010 this was removed to the National Museum of Scotland. The only working telescope is a 20-inch (0.5 m) reflector that was installed in 1967 in a hemispherical dome on top of the teaching laboratories. This telescope is used for undergraduate teaching.

After contacting the Royal Observatory Edinburgh my suspicions were proves to be correct. Manythanks to William D Taylor for kindly supply the above image.

2012, the 20 inch telescope is moved from Edinburgh to a new home, the James Irwin observatory in Kent, full details are here: http://www.stfc.ac.uk/News+and+Events/38790.aspx and here, http://www.bbc.co.uk/news/uk-england-kent-17513808
