Great Melbourne Telescope
The Great Melbourne Telescope was built by Thomas Grubb in Dublin, Ireland in 1868, and installed at the Melbourne Observatory in Melbourne, Australia in 1869. In 1945 that Observatory closed and the telescope was sold and moved to the Mount Stromlo Observatory near Canberra. It was rebuilt in the late 1950s. In 2003 the telescope was practically destroyed in a severe bush fire, but a project to restore it to working condition is under way.
== Specifications ==
The telescope had a speculum primary mirror, and was mounted on an equatorial mounting, enabling it to track the stars accurately as they appeared to move across the sky. The design had been approved by a committee of leading British astronomers and scientists.〔Robinson, T. R. & Grubb, Thomas. (1869). 'Description of the Great Melbourne Telescope,' ''Philosophical Transactions of the Royal Society of London'', 159: 127-161.〕
At the time of commissioning it was the second largest telescope operating in the world, after Lord Rosse’s 6 foot reflector at Birr, Ireland, and it was the largest fully steerable telescope in the world.
The telescope was designed to explore the nebulae visible from the southern hemisphere, and in particular to document whether any changes had occurred in the nebulae since they were charted by John Herschel in the 1830s at the Cape of Good Hope.〔Melbourne Observatory. (1885). ''Observations of the Southern Nebulae made with the Great Melbourne Telescope from 1869 to 1885'', Part 1, Melbourne: Government Printer.〕
