The Norman Lockyer Observatory is both a historical observatory and home to an active amateur astronomical society. It is a centre for amateur astronomy, meteorology, amateur radio, and the promotion of science education.
The observatory is regularly open to the public, staffed entirely by volunteers, and each August hosts the South West Astronomy Fair.
Norman Lockyer was a Victorian amateur astronomer, who discovered the element Helium in the Sun's corona in 1868 and was one of the founders of the science journal Nature in 1869. He became the director of the Solar Physics Observatory at South Kensington and the first professor of astronomical physics in the Normal School of Science (now the Royal College of Science) in 1887. He was knighted in 1897.
After his retirement to Sidmouth, Lockyer obtained support in 1912 for the building of the Hill Observatory, renamed the Norman Lockyer Observatory following his death in 1920.
