Coelostat shed

The Coelostat shed was used to photograph the Sun. The coelostat was first erected in Labrador (bottom) for the total solar eclipse in 1905 but the event was clouded out. It was then mounted in its own shed in Ottawa (top) and used to monitor solar activity from 1905-ca. 1965. Canada Science and Technology Museum
