Summary: A photoheliograph is an instrument for photographing the sun, consisting of a camera and a specially adapted telescope. The Kew Photoheliograph was the first astronomical instrument specifically designed for photographing celestial objects. "Designed for the Royal Society by Warren de la Rue in 1857, it was built by instrument maker Andrew Ross, London. First installed at Kew Observatory, it was used to take regular photographs of the Sun."

  • Help the British Library tag a million images

    Some of the million images the British Library have released on Flickr Commons have been added here for you to play with. The tags you add will help people find these historic images.

    They have asked people to use these special tags where appropriate: 'map', 'letter'+theletter e.g. LetterA, 'architecture', 'decoration', 'landscape', 'music', 'portrait', 'fashion'. If the image needs rotating, add 'rotatec' or 'rotatecounterc'.
