Ewell Astronomical Society was founded by Phil Ringsdore in 1966 with Sir Patrick Moore as its patron. Following Sir Patrick’s death in 2012, Professor Ian Morison accepted an invitation to become the society’s patron. A position he still holds.

The society has the use of an Observatory housed 11 inch Schmidt-Cassegrain Telescope installed at Nonsuch High School where we hold regular informal observing sessions. We also hold regular observing sessions at Headley Heath and Ranmore Common near Dorking under dark skies.

We can provide talks, demonstrations and guided viewing sessions for schools and groups such as Brownies, Guides, Cubs and Scouts.

We are sad to announce the passing of our patron Professor Ian Morison on 13th April.
He was a good friend of the Society and over the years gave us many talks along with advice and guidance on Astro Imaging to our members.

He will be sadly missed.

We have resumed our monthly meetings and regular observing sessions.

See below for potential 2024 observing dates (weather permitting).
