About Us - Introduction

The Society Today

The Society hold lecture evenings in the Junior Hall of the Royal Russell School, Coombe Lane, Croydon, Surrey CR9 5BX every second Friday during term, and there are more details are on our Meetings page. Meetings start at 7:45 pm and end by 10 pm. We normally start with an introductory talk and society news followed by a short refreshment break. The main lecture/talk occurs next and the meeting is completed by the raffle draw and closing remarks.

A map is available showing the location. Cars should be left in the car park on the left as you enter the school. Visitors are requested to sign the attendance register (safety reasons) just inside the meeting room.

We currently have a membership of about 100 and generally get 25 to 45 people at each lecture.


The Croydon Astronomical Society is a registered charity whose objectives are to help and educate members and the public to acquire a knowledge of astronomy and related subjects. The society does not charge a mandatory subscription but instead rely on the generosity of our members and visitors in donating what they can afford as well as buying tickets for our raffle, which is a feature of the lecture evenings. Donations are used to finance the activities of the society.


The Society is governed by its constitution. The constitution lays down the ground rules for the society and a copy has been lodged with the Charity Commission as we are a registered charity.


We have a reference library at our observatory at Kenley which contain books that are useful during observing.

History of The Croydon Astronomical Society

We were founded as the Croydon Group of the Junior Astronomical Society on 5th May 1956, and becoming the Croydon Astronomical Society in 1965.


Membership - Joining the Croydon Astronomical Society

How to join the Society

Newcomers and guests tend to visit for a few meetings to determine if membership is for them. However, membership is open to all at any time and is encouraged.

All you need to do to join the society is to come along to any of our meetings at the Royal Russell School or to our observatory at Kenley and fill in a membership form; alternatively complete a membership form and give or post to us . Our constitution requires that members reaffirm their membership every year so a new form will need to be completed once a year. We use the same form, both for new members to join our society and existing members to reaffirm.

Our membership year starts on the 1st September and ideally a form should be completed by October, but later is still okay. You need to have filled in a form in good time to attend the AGM or if you wish to stand for any of the committee posts. Details of why you are required to reaffirm your membership are in the FAQs.

How much does it cost to join?

There are no mandatory fees to join the society and no obligatory fees to attend the meetings. To finance the activities of the society we ask members for donations and we also hold a raffle at the Royal Russell School meetings. No committee member is paid personally for any work; we are all volunteers.  We ask those who are eligible to complete a Gift Aid form.

We have produced a list of Frequently Asked Questions.  Alternatively contact us for further information
