Minor planet guider

Astronomical equipment, minor planet guider, metal / wood / plastic, designed by Harley Wood, made by H F Pinnock, Sydney, New South Wales, Australia, 1954, used by Sydney Observatory, New South Wales, Australia, 1954-1964 A device that provides the facility to give the wires in a guiding telescope a motion corresponding to the reverse of the predicted motion of an asteroid or comet. The device assists in concentrating the telescope to focus on the faint light of minor planets instead of the brighter lights of stars. The device is fixed to a rectangular wooden platform. On one side of the platform metal supports hold a metal disc at a slight angle. The disc can turn with the assistance of a wheel driven spoke fixed on the other side of the platform. Electrical components to drive the device are fixed behind the spoke. Connected to the electrical components is an electrical cord sheathed in fabric. A three pronged plug is attached to the end of the cord.

  • 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'.
