The Cardiff Astronomical Society (CAS)

Introduce legislation to combat light pollution

Light pollution does not only steal from us our stars, but also has massive negative implications for both people and the environment.

Therefore, steps should be taken to reduce light pollution, particularly in areas where it has the greatest impact on the wellbeing on humans or other species.

Sign petition

The CAS Observatory at Dyffryn Gardens is a major asset of the Cardiff Astronomical Society and we are keen that it is used as the hub of society observing events from beginner to advanced practitioner.
Two types of event are regularly scheduled with a typical frequency being once a month, the dates and times of upcoming events can be found below and will be publicised elsewhere e.g. Website, Twitter, Facebook, Newsletters and at Society Meetings. There may also be events arranged to coincide with specific astronomical occurrences.

Star Parties

Star Parties are usually held on a Tuesday night. These sessions are ideal for our junior members and anyone else who wants to learn their way around the night sky. Each event will start with a general sky tour.
We will not be concentrating on faint fuzzy objects, but the brighter Messier objects, the Moon and bright planets. We will try and show you how to observe and what little tricks to use to help locate things. You may learn something, you may not, but we promise they will be light hearted and fun.
Star Parties will run from 7.30 to 9.30 p.m. unless otherwise stated. Please note that all private equipment brought to CAS events is not insured by CAS and therefore CAS shall not be held liable for any damage or loss. The owner of the instrument is responsible for the safe and proper use at all times in accordance with manufacturer's instructions.
