[70] The Yerkes, although just 4 inches in aperture larger, meant an increase of 23% in light-gathering ability. [71], *Note the Leviathan of Parsonstown was not used after 1890. For example, the Leviathan of Parsonstown was a 1.8 meter telescope with a speculum metal mirror, but getting good astronomical results from this technology could be difficult, and another large telescope of this period was the Great Melbourne Telescope in Australia, also a metal mirror telescope.
