Croydon Astronomical Society

The Society holds public talks at our new venue - the Sandison Room in Trinity School, Shirley Road, Shirley Park, Croydon, CR9 7AT. These are held approximately every other Friday during school term time and are open to the public. We plan to re-start our talks in September.

We also have an observatory, near Kenley historic aerodrome. There is a clubhouse for visitors and a kitchen for hot drinks (but no toilets).


We try to open to the public (free, no need to book) on any Saturday night when it is clear.  Information will be posted here and also on the society's Facebook page


Parking (observe restrictions) is nearby in Hayes Lane just a couple of hundred metres to the south at the Royal Air Force Kenley Tribute.


We sometimes open the observatory on other days/nights, for example for solar viewing.  Click HERE for any upcoming events.

You can book a Group Visit for groups of children (school groups, scouts, cubs etc) or adults. These are normally arranged during the week.  We are now taking bookings for group visits.  There is a small charge for this. Click HERE for further details or to make an enquiry.


Thinking of buying a telescope or just got one and want help setting it up?  We can probably help. Contact us.
