Beginning as the centre of scientific research for the colony of New South Wales, the Sydney Observatory has played a seminal role in the history of timekeeping, meteorology and astronomy in Australia. Today it is a museum and public observatory, and is listed on the NSW State Heritage Register for its significance. It contains a 29-centimetre lens telescope made in 1874, a 42-centimetre computer-controlled telescope and a hydrogen-alpha solar telescope.
