From 1974 to 1979, Roy Dancey and National Research Council Canada staff at the DAO worked on grinding, figuring, testing and polishing the 14-ton, 141-inch Cervit glass mirror for the new Canada-France-Hawaii Telescope in Mauna Kea, Hawaii. Canada and France contributed equally to cover 85 per cent of the cost of building it. The machine used to work on the telescope was custom built in Vancouver. Photographs at the end of this video show DAO staff in 2009 and an image of the Orion Nebula captured by the telescope.
