[3] For a short time around 1915 the society had a "Telescope House" on Tanna Hill in the grounds of the Otago University.
A site near the Dunedin Botanic Gardens was selected, but construction was delayed by World War I.
[4] In the 1960s the society built an annex on to the observatory to provide a more convenient area for meetings, talks and telescope construction.
A talk was then given by amateur astronomer Dr. Grant Christie of Auckland's Stardome Observatory concerning the changes in our understanding of astronomy and the universe during the last 100 years.
The first meeting of each month generally features an astronomy related talk presented by a society member or an invited speaker.
The second meeting of each month focuses more on practical astronomy in the form of an observation session (if the weather is kind), or discussion and examination of astronomical equipment and techniques.
During winter months (when daylight saving time is not in force) the society opens the Beverly-Begg Observatory to the public on Sunday nights starting at 7:00pm.
