Welcome to

Croydon Astronomical Society is based in Croydon, just a few miles south of London. We hold public talks approximately every two weeks during school term time and aim to open our observatory to the public every Saturday evening.   The society was founded in 1956 and operates through the donation of time from its members and donations of money from its members and visitors.   If astronomy is your thing, please consider joining us as a member.  

Public opening of the Observatory

Summer openings.

​

In the summer months it never really gets dark enough for observing.  Because of that we have paused our regular Saturday openings until the autumn.  We may still open on special occasions - keep watching here and on Facebook.

We have an observatory near Kenley aerodrome which we aim to open to the public each Saturday evening. Whether we can open depends on the weather (and availability of volunteers).  We can't open if it is wet, windy or cloudy.  As the weather is often quite changeable we sometimes can't make the final decision about whether we can open until mid-afternoon on Saturday.  We post messages on our Facebook page  and our answerphone (07719 339336).

We also post our decision here.  Please check before you set off to visit us.

Why we're here

Our objectives are to advance education in the science of astronomy and related subjects for the public benefit in Croydon and the surrounding area by:

 

  • encouraging a popular interest in astronomy and allied subjects;

  • helping beginners, irrespective of their age, to acquire a knowledge of astronomy and allied subjects; and

  • providing facilities for practical work and active participation in astronomical observation.
