Croydon Astronomical Society present a series of talks on subjects related to astronomy on Fridays.  From September 2021 these are held in the Sandison Room at Trinity in Croydon. 

The meetings start at 7.30 pm and are open to anyone. 


There is no need to book; just turn up.

For details of car parking, a map and access by public transport click here.

There is no charge for the talks but there is a suggested donation of £3 per person to help cover the costs of venue hire and the speaker (larger donations are of course very welcome).  Refreshments are available for a nominal charge.

The talks programme is shown below.   This is always provisional and subject to last-minute changes. We will update this programme as we know more information.

Please see the rules we ask visitors to follow.
