Who We Are and What we Do

Just north of Southampton, in the quiet village of Toothill, stands one of the finest observatories in Hampshire.  It houses a 14″ Meade and numerous smaller telescopes.

Owned and run by Solent Amateur Astronomers, its doors open regularly to the public, when everyone is most welcome – see schedule of open nights.

The observatory will not open if it’s cloudy/raining. Please check our Facebook page on the Saturday morning for an update as to whether we will be opening.

We also have a comprehensive programme of talks at Oasis Academy, Lordshill to which the public are also invited.

Solent Amateur Astronomers is now a Charitable Incorporated Organisation – Registration Number – 1206419.
The Obsevatory Address is: Toothill Reservoir, Upper Toothill Rd, Romsey, SO51 9LN.
