Kowethas Steronieth Kernow



 Cornwall Astronomy Society (Kowethas Steronieth Kernow) is a friendly, relaxed group of amateur enthusiasts with interests in many areas of astronomy, cosmology, observing, astrophotography and telescope building.

Our objectives are to foster the practice and enjoyment of
astronomy, cosmology and related interests.

We have two regular meetings a month.

The first is on the 2nd Tuesday of the month, starting at 8pm at Degibna Chapel, Helston TR12 7PR, & will feature viewing afterwards, weather permitting.

The second is on the 4th Thursday of the month, starting at 8pm, at the Mabe WI Hall, Antron Hill, Mabe Burnthouse, TR10 9HH. 

We also hold regular out-door viewing events (weather permitting).

Visitors and beginners are welcome(Under 18yr olds must be with parent).

Refreshments are available at club meetings.

This website will be updated regularly with information relating to forthcoming events.


 If you need any help getting started in Astronomy pop in to any of our meetings, just bring along your scope and/or any questions you may have.  You are also welcome to post your questions here or on our facebook site, we will try our best to help you.
