CAS Statement of Safety Considerations and Policies

The Society is keen to ensure that all Society members and other visitors to the CAS Observatory and other events in which the Society is participating are kept as safe as possible. For this reason the Society produced a few years ago a clear statement of its policy in this area including the responsibilities which CAS members and other visitors to Society events themselves have.

We urge YOU to read the Statement which can also be found among the Important Documents in the Members' Area of the website.


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 Physics and Astronomy Department of Cardiff University which, we were pleased to see, was named University of the Year at the 2017 Business and Education Partnerships Awards. In addition, regular night sky (and occasional solar) observing sessions are held 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 or binoculars. It's also possible to try us out before joining!
