Refractor telescope inside the main dome at Sydney observatory
This telescope was installed in the South Dome at Sydney Observatory in 1874 and is now the oldest working telescope in Australia. It was used by Henry Chamberlain Russell, Government Astronomer at Sydney Observatory from 1870-1905, to view the transit of Venus that occurred on 9 December 1874. The telescope is therefore important because of its use in the observation of a rare astronomical event, as well as for its age and its connections to the history of the Sydney Observatory site and the early astronomical community in Sydney.
