COSMOS Observatory Open Evening
Tuesday every week from April 2022 to October 2022
COSMOS Observatory
Signal Row, St Martins, Isles of Scilly, TR25 0QN, South West
Join the friendly and experienced team of astronomers at the Community Observatory St Martins on Scilly (COSMOS) and experience the truly wonderful dark skies above the Scilly Isles during this one of the facility’s regular Tuesday evening open nights that occur from April through to October.
Sessions are split into two, each with a maximum number of ten people, prior booking is therefore advised.
Whilst the skies may not get dark through Summer there will still be plenty to see and therefore is very much worth a visit!
