COLOSSAL INSTRUMENT The London Illustrated News dedicated a full-page review to the Great Melbourne Telescope in November 1868. The writer enthusiastically described the mechanics of the Cassegrain focus, which gave the telescope "some important advantages, foremost among which is the fact the observer is never more than about 4 ft. off the ground." The benefits of the lattice-work optical tube were listed as "great stiffness and freedom from tremor, combined with lightness and freedom from currents of air . . ." The scope was also praised for its "improved" equatorial mounting and "efficient photographic apparatus." Australian groups are restoring what was once the world's largest equatorially mounted telescope.
