We have a new room for our meetings held at, St John's Church Hall. You can also join us online.

Mexborough & Swinton Astronomical Society (MSAS) is a registered charity, its objects being: the advancement of education for the public benefit in astronomy and its associated sciences. Formed in 1978 with just five members and meeting in members' front rooms over the years, the society has grown into a group of about 50 members who meet every Thursday evening.

The Society also owns and runs its own observatory at nearby Hoober Stand. The J. A. Jones Observatory is named after one of our members and houses a recently upgraded set of equipment. This includes a Paramount ME, 14 inch Celestron and a 5” Takahashi TOA Telescope. This gives society members an excellent set of instruments to observe the night sky.

The society’s weekly programme consists of lectures and talks given by a wide range of visiting speakers and members as well as training, where more experience observers pass on their skills to new ones and where skills can be honed and updated.

We hold several telescopes, including a solar scope for members to loan. We are also the proud owners of an upper stage of a Skylark research rocket!
