Join the Cardiff Astronomical Society

The Cardiff Astronomical Society is a thriving society located in South-East Wales and it promises a warm and friendly welcome to all! So why not join some of the Society's 300-plus members at one of our meetings or at an observing session?!

By joining the Society you can -

  • attend our fortnightly (September to July) talks*
  • borrow the Society's telescopes
  • use our Library
  • attend our regular (weather permitting) star parties and observing sessions*
  • use the Society's Observatory at Dyffryn Gardens**
  • enjoy our various social events, day trips etc.

* We allow prospective members to attend a couple of sessions/talks so they can meet us and see what we do but they would be expected to join the Society if they wished to continue attending.

** Subject to attending an observatory induction session.

We have three categories of membership as follows -
