The Projectors
Armagh Planetarium has used a series of projectors of increasing sophistication and capability. The first projector was the Goto Mars (1968-1977), an example of advanced 1960s technology. It included individual lamps to project images of the Sun, Moon and planets. This was followed by a Viewlex-Minolta Roman IIb (1977-1994), which is still in use in its current home at South Downs Planetarium in England. The first digital projector installed in Armagh was an Evans and Sutherland Digistar 1 (1994-1995). Armagh was the first planetarium in the UK to use this new technology but it was soon replaced by the even more advanced Digistar 2 (1995-2006). The latest Digistar 3 is a new state-of-the-art computer system projecting full-colour fulldome video across the entire dome.
