Mike,

The South dome houses an 11.5" refractor. It was built in 1874 and is the oldest working telescope in Australia.

Don't quote me on the following but I will have a stab:-

Built by Hugo Schreider in Germany.
Focal ratio is about F14.

As you could appreciate this scope being a 130 year old achromat is not up to the quality of modern day apochromatic refractors but has a lot of historical significance.

Greg Bryant or one of the observatory night guides like Les Dalrymple can probably tell you a lot more about it than I can. I have looked through it a few times during past observatory visits. It is a historical work of art.
