[4] The Observatory's historic instruments are associated with Lockyer's pioneering work on star temperature which led to theories of stellar evolution and the foundation of astrophysics.

[citation needed] The Connaught Dome, which incorporates 'Lockyer Technology Centre' (the observatory's radio astronomy facility), was opened in 2012.

[6] The observatory provides modern telescopes with computer enhanced imaging, maintains some of the nation's most historic astronomical instruments and enjoys a relatively dark night sky with a southerly aspect across the sea.

The observatory celebrated its centenary in 2012, with commemorative events throughout the year, as well as the openings of the Connaught Dome (20" reflector) and Lockyer Technology Centre by Brian May.

The facility is financed solely by its membership, private donations and income derived from Public Open Days.
