Description: | Kew photoheliograph designed by Warren De la Rue for the Royal Society, London, in 1857 and made by Ross, London. Used for daily photography of the Sun at the Kew Observatory and Royal Observatory, Greenwich. Transported to Rivabellosa in Northern Spain where it was used to photograph the eclipse of the Sun on July 18th 1860. Similar photographs taken by Father Secchi 500 km away showed identical prominences which proved that they were integral to the Sun rather than terrestrial atmospheric effects.. | License: | http://creativecommons.org/licenses/by-nc-sa/2.5/ | Subjects: | photoheliograph | Temporal: | 1857 | Source: | Science Museum | Creator: | De La Rue, Warren | Identifier: | http://collectionsonline.nmsi.ac.uk/grab... | Go to resource |
