Equatorial twin telescope. 19th-century illustration of designs for the equatorial twin telescope at the Radcliffe Observatory, Oxford, UK. The Radcliffe Observatory functioned as an observatory for 160 years from 1773 until 1934. This 18/24-inch twin refractor telescope was built in 1901, and was transferred to the University of London Observatory. It was constructed by the Grubb Telescope Company, led at the time by Irish telescope engineer Sir Howard Grubb (1844-1931). This design was originally printed in the article 'Equatorial Twin Telescope at the Radcliffe Observatory' in the 21 December 1906 issue of 'Engineering News'.
