[1] The telescope is a 12½-inch (32 cm) Newtonian reflector solidly fixed on a polar mount.
This is housed in an observatory with a rotating hemispherical dome moving on rollers.
Established in the 1920s, it was disused during the 1940s and 1950s after it was taken over by the RAF during World War II and damaged.
The telescope was fully operational until the late 1980s when its components were stolen during the 1987–89 Insurrection.
