The Society holds lecture evenings at the Royal Russell School, Coombe Lane, Croydon, Surrey CR9 5BX. These are held every second Friday during term time more details are on our Programme page. Lectures start at 7:45 pm and end around 10 pm. We normally start with an introductory talk and club news followed by a short refreshment break. The main lecture/talk, as shown in the programme, occurrs next and the meeting is completed by the raffle draw and clsing remarks..
A map is available showing the location. If you visit the school the clue to finding the lecture theatre is to look for the large building with a floodlit clock on top - this is called The Great Hall. The lectures are held in the basement of The Great Hall, the entrance is located at the far end of the building at the far side. Cars should be left in the car park on the left near the entrance. Visitors are requested to sign the visitors book in the Lecture Theatre when they arrive..
On Fridays where there is no lecture we hold informal lectures and carry out practical observing using the Society’s 14-inch and smaller telescopes located at our observatory at Kenley. It is advisable to wear warm clothing as the observatory is not heated. Members and visitors are required to record their visit-times in the logbook at Kenley when they arrive and when they leave.
We currently have a membership of about 100 and generally get 25 to 45 people at the lectures.
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 allied subjects. The CAS does not charge a 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 - a copy can be found here in PDF format. (Please note that this is a word processed version of the original typewritten copy. In the event of any differences the original typewritten copy takes precedence). 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.
The society library, almost as old as the society itself, was decommissioned summer 2016 as it was realised that with alternative sources of information, lending reduced to near nil. The cabinet is still in use for storage and many books still remain, which are available to members upon notifying a committee member.
In addition we have a reference library at our observatory at Kenley which contain books that are useful during observing.
