The Peter Harrison Planetarium
is a 120-seat digital laser planetarium, situated in Greenwich Park
, London and is part of the National Maritime Museum
. It opened on May 25, 2007.
The planetarium uses Digistar 3
software with blue, red and green lasers and grating light valve
(GLV) technology to create a 4,000 pixel strip. This strip is swept to produce a 5,000 by 4,000 pixel image, refreshed 60 times per second. The image is projected through a fisheye lens
onto the dome of the planetarium.
The planetarium is housed inside a 45-ton bronze-clad truncated cone, tilted at 51.5<sup>o</sup> to the horizontal (the latitude of Greenwich), and stands parallel to (but 50 metres east of) the prime meridian
. It was conceived under the then Director, Roy Clare CBE, as the centrepiece of the "Time and Space" project, a £17.7m re-development of the Royal Observatory, Greenwich
, and funded with a £3.25m grant from the Peter Harrison Foundation.
