The Cardiff Astronomical Society (CAS) is a thriving society located in South-East Wales. It has been in existence for over 40 years and is one of the largest amateur astronomical societies in the UK. CAS continues to provide a range of facilities for both Society members and the public at large including a varied programme of talks on Thursday evenings (except in August) at the Cardiff University's Physics and Astronomy Department (off Newport Road) and regular night sky (and occasional solar) observing sessions at the Society's own Observatory at Dyffryn Gardens.

Our members come from all walks of life and their knowledge of astronomy ranges from complete beginner to advanced. You don't need any specialist knowledge to join us and neither do you need to own a telescope. It's also possible to try us out before joining!

More details about the Society and what it does are available here

We are keen to get more Society members on board to assist with the running of CAS events - please see here how you can Help Us

Upcoming CAS events

Unless CAS members are attending as part of the outreach team they will need to purchase a ticket see here
To book a ticket please contact Dyffryn Gardens by phoning: 029 2059 3328.
Thinking of helping out? This is what member Ian Mclean said after he came to Brecon on October 14th:
It was my first time and I must say that it was fantastic. The fact that the clouds cleared made the whole evening even better. I'm now looking forward to Dyffryn on the October 28th. See you all there!
