SPA/CAS Talks Videos

The Society for Popular Astronomy (SPA) held a special meeting in conjunction with CAS on 28th September 2018 at Cardiff University.

The SPA have now sent us the videos they made of the three talks -

  • Prof Ian Robson - The Changing Scene of Astronomy
  • Philip Wallace - The Birth, Life and Death of Stars
  • Dr Megan Argo - When Galaxies Collide

Gift Aid

CAS is now registered for Gift Aid. This means that, if you are a UK taxpayer, we can claim back the standard rate tax on subscriptions (and on any donations) paid since the Society became a registered charity on 31st October 2016 (giving an effective 25% boost to the amount the Society has received).

However, in order to reclaim these monies from HMRC, we need all members who pay tax to complete and sign a Gift Aid Declaration form.

Please note that if you have paid your subscriptions by PayPal, you will have already been asked if you would consent to those subscriptions being Gift Aided - but we still need a completed and signed Gift Aid Declaration form in order for us to reclaim the tax paid as Gift Aid.

If you are eligible, please take a form (see the button to the right) and then complete & sign it and pass it to us at one of the fortnightly talks or send it to CAS by post or email (as shown at the bottom of the form).

Thank you for your help.

A New Initiative - Discussions Prior to the Fortnightly Talks

We have started a series of informal meetings at which members can discuss astronomical topics with other members. These sessions are held immediately prior to some of the scheduled fortnightly talks (6.45-7.30 p.m.) and take place at the back of the lecture theatre. If members present want to continue the session after the talk there is a coffee area on the ground floor of the Queen's Buildings and the nearest Wetherspoons pub is just down the road.

The most recent session was held in advance of the talk on 18th October 2018 and was on 'Helping (in any way members can) at activities such as Star Parties and Public Events'. It followed the inaugural session held on 20th September 2018 which was on 'Aligning Your Telescope'.

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. 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!
