CAS Outreach events at Brecon Beacons Mountain Visitor Centre

Further to our successful SAFE Solar viewing in June (scroll down to see photos of the day) we have been invited to take part in two further events at the visitor centre in September, as part of the Brecon Beacons Dark Skies Festival.

The first is a stargazing evening, in conjunction with Dark Sky Wales, on Friday September 16th at 8pm. Tickets are £20 which includes Coffee and Welsh Cake to get your evening off to a great start. Further information can be found on their Facebook page here or on the Eventbrite page where you can buy TICKETS HERE. Please note: CAS members will have to buy a ticket just like a member of the public unless they are actively working on the evening as part of our outreach team, with a scope, binoculars, engaging the public, manning our stand etc.

The second event is on Saturday 24th September from 10am to 4pm and is another SAFE Solar viewing event. This event is free although there is a charge for parking. There is no need to book a time slot but register your interest here CAS Solar Event

There are also non CAS events as part of the festival including Planetarium shows (£5.98) and free stargazing with Usk AS. To see the full program click Brecon Beacons Dark Skies Festival

For further information on the facilities available at the visitor centre and for directions on how to get there please see here

By attending one or both events you can pick up tips and advice about pursuing this fascinating interest, meet like-minded people, chat about all things astronomical, view some celestial objects from a dark site, attend a talk and try out some specialised equipment to view the Sun. It would be wonderful if you decide to join us, you can be assured of a warm welcome - it's what we do!

The talks programme for next season is currently being compiled. We have a number of talks already booked and a number in the pipeline where we are awaiting confirmation of dates. You can view the current position using the dedicated tab at the top of the home page. Talks will be updated as they are confirmed so check back regularly for the latest position.

Monthly CAS Social (Tuesday Evening) via Zoom (Members Only)

Once a month on a Tuesday evening from 19:30 to around 21:00 we hold a social get together on zoom where we chat about both astronomical and non-astronomical subjects, have a quiz and have presentations by members. These will continue running until September with the next meeting being held on August 9th. The presentations are usually on either member's hobbies or their travels but can be on anything they think others will find interesting.
Why not come along one week to see what you think. You do not need to stay for the whole session and people often arrive late or leave early because of other commitments. It is very informal!
To register your interest email please include your Membership Number and you will be sent a link to the next session.

Photos from Cardiff Astronomical Society SAFE Solar Gazing Event at Brecon Visitor Centre 25th June

A day of Sun and heavy showers but we were outside more than we were in.

We had a good number of (international) people interested, some had travelled especially to see us and it worked well on the balcony with quick access through the door at the end to a dry area where we could keep scopes, glossies, laptop and us dry! And this time round we even had a sunspot to show people.

Many thanks to STFC for supplying the wonderful resource material, informative leaflets, posters, workbooks and freebies for us to hand out so that people had a better appreciation of what they were looking at.

All in all, another success to chalk up and it was good to be back in the outreach business.

Introduction to CAS

The Cardiff Astronomical Society (CAS) is a thriving society located in South East Wales. It has been in existence for over 45 years and is one of the largest amateur astronomical societies in the UK. CAS provides 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!

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


Come and join some of the Society's 275 members at one of our talks or observing events. We promise a warm and friendly welcome for all. Only £15.00 per annum also means you can make use of our Library

Gift Aid

CAS is 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) 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 return a Charity 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 Charity Gift Aid Declaration form in order for us to reclaim the tax paid as Gift Aid.

If you are eligible, please take a form (using the button opposite) and then complete it and pass it to us at one of the fortnightly talks or send it to CAS by post or email (see the bottom of the form). Thank you for your help!

Society help for schools etc



As shown here, Cardiff Astronomical Society welcomes all invitations from organisations such as colleges, schools and guide/scout/brownie groups located in Cardiff and surrounding areas for an outreach stargazing/astronomical event for all ages and levels of knowledge. Society members very much enjoy bringing our passion for the subject to a wider audience and helping everyone to get started in this fascinating subject. We do not charge a fee for our expertise and participation; the enjoyment is enough reward and we will do our very best to ensure a worthwhile and enthralling evening. We would, however, be grateful for reimbursement of travelling expenses and petrol costs to venues outside of Cardiff and its environs. Otherwise the cost would fall on individuals and the non-profit-making Society. It should be noted that CAS has a formal Policy on Child Protection and the Protection of Vulnerable Adults
