The site and buildings

The Section's Observatory is located at Rue du Lorier, St Pierre du Bois, Guernsey, about 100 metres up the road from La Houguette School.  It was opened in April 1991 by Heather Couper and Nigel Henbest, and a further roll-off roof building was opened by the late Sir Patrick Moore in 1993.

The main building was constructed in 1943 as part of the German Mirus gun battery complex.  It is contains a meeting room suitable for up to 20 people.  An adjoining room contains a library and basic kitchen facilities.  The nearby telescope building  has a motorised roll-off roof.  It houses the 16-inch Meade reflecting telescope and 5-inch refractor.  Externally there is a concrete pad with electricity supply, for placing telescopes, especially the 11-inch Celestron.  Space for additional telescopes is provided by a grassed area.

Instrumentation includes:

§  16-inch (40 cm) LX200 Meade computerised catadioptric telescope, permanently mounted on a concrete pier in a building with a roll-off roof.

§  5-inch (12.5 cm) Takahashi refractor, mounted on the 16-inch telescope.

§  All-sky camera.  Click here for link to live images.
