Colney Lane Observatory [CLO] (c.1976-1994), Colney Lane, Norwich, established by the Norwich Astronomical Society to house a 30-inch reflecting telescope on a fork mount in a hemispherical dome, built and designed by members of the group. The site, owned by University of East Anglia, was designated for two new hospitals. Due to the light pollution off the development the observatory was displaced to a new site near Seething airfield. The large reflector was moved here but was subsequently replaced, first given to Breckland Astronomical Society, but later re-erected at Reepham High School (Mitchell 2017; Humphrys 2002).
Brecklands Astronomical Society Observatory [BASOG] (2000- ), Great Ellingham Recreation Centre, Great Ellingham, established by the Brecklands Astronomical Society. The domed building houses a 20-inch reflector on a computer controlled Dobsonian mounting.
Green House Farm Observatory [GHFO] (2006- ), Green House Farm, Wiveton, established by the North Norfolk Astronomical Society. A run-off roof building houses the restored ‘Walter Goodacre Telescope’, 12-inch Calver reflector on its equatorial mounting (Anderson 2019).
Reepham School Observatory [RSO] (2000- ), established by Reepham High School as a teaching facility. Equipped with a 30-inch reflecting telescope on a fork mount in a hemispherical dome, built and designed by members of the Norwich Astronomical Society. The telescope was first located at their Colney Lane site then briefly at their Seething Observatory. It was then given to Breckland Astronomical Society before it came to the school (Mitchell 2017).
Stuckey’s Observatory [StOC] (2014- ) Cromer, established by Mark Stuckey using Horace Dall’s 15½-inch Dall-Kirkham reflector, which is installed in its restored original domed observatory building (LAS 2014, p.13).
Seething Observatory [SOSN] (1994- ), Seething, established by the Norwich Astronomical Society after displacement from their Colney Lane site due to building development. The site houses two domed buildings containing a 14-inch SCT catadioptric telescope (7-m dome) and an 8-inch Cassegrain telescope (Herschel Dome). A 30-inch reflector from the former was located here until 1999 – now at Reepham High School. The observatory also is provided with numerous observing platforms, a run-off shed for imaging and a Springfield telescope on an open-air pillar (Mitchell 2017).
