Peter Harrison Planetarium

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, 2007.¹

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.²

The planetarium is housed inside a 45-ton bronze-clad truncated cone, tilted at 51.5^o to the horizontal (the latitude of Greenwich), and standing on the prime meridian.³ It was built as part of £17.7m re-development of the Royal Observatory, Greenwich, and funded with a grant from the Peter Harrison Foundation.¹⁴
