Parramatta Observatory plans. Plans of the observatory in Parramatta, Sydney, Australia, which was completed in 1822. This observatory was financed completely by Sir Thomas Brisbane, who employed two notable astronomers, Christian Carl Rumker and James Dunlop. By 1825, the locations of 7385 stars had been determined and in 1835, the Catalogue of 7385 stars was published. These plans, drawn by Reverend W. B. Clarke in 1825, published in 1835, show the building's simple structure made of wood and canvas, with two metre sandstone piers.
