Description

Photograph of the observatory building for the seven inch aperture heliometer at the Cape Observatory, South Africa. Made by Repsold and Sons, Hamburg in Germany, the instrument has a split main lens that is used to measure very precisely the angular separation of objects in the heavens. Sir David Gill (1843-1914), Scottish astronomer, used this heliometer to determine stellar and solar parallax to measure the distance to nearby stars and that of the Sun.
