It aims to be inclusive, promoting and nurturing an interest in all branches of science, while catering for wide levels of knowledge, from layman to expert alike.

The society maintains specialist astronomy and meteorology sections and runs a programme of lectures on various scientific topics in the Hampstead area of North West London.

Following Wilks' retirement, in 1910 Patrick Hepburn of the British Astronomical Association (BAA) joined the society, becoming its joint secretary with Vizard.

In 1967 H.N (Ron) Irving was commissioned to overhaul the telescope's mounting, drive and clock, a job he carried out at a highly subsidised rate and was granted honorary life membership as a result of his generosity.

In 1971 Herbert Stark, who was HSS general secretary from 1966 to 1974, set-up a sub-committee, headed by Doug Daniels, to focus on the observatory's repair and maintenance.

This precipitated the formation of ATMoL/CATS as it is today, a non-profit subscription per term funded class, still under the tutelage and mentorship of Terry Pearce and continues its affiliation with the Astronomy section of the HSS.

From 2016 the Camden Astronomy & Telescope-making Society's home has been the Holly Lodge Community Centre in Highgate and classes are fortnightly on Wednesday evenings.
