Be prepared for the (not-so-)great eclipse

Brian Cox quote

SPA Convention is a huge success! 

Our latest Convention, held at the Institute of Astronomy, Cambridge, on 1 April, was a great day. We welcomed around 200 members to hear talks from leading scientists, tour a varied exhibition, and see the university telescopes, with the bonus of a daylight view of Mercury through the historic Northumberland telescope (above)
