Blackett Observatory

Blackett Observatory

Marlborough College, Marlborough, Wiltshire, SN8 1PA

The Blackett Observatory is located within the private grounds of Marlborough College. It is home to an incredible 10″ Cooke refractor steeped in history that offers stunning views of the Cosmos! Observing is organised by the observatory’s enthusiastic Director, Charles Barclay.

The observatory is not often open to the public; however, the facility is accessible to those outside the College interested in Astronomy. Becoming a ‘Friend of the Marlborough telescope‘ costs just a few pounds per year, less than a single ticket to attend some other observatories. In return, you will be given access to their diary of events, arrange private visits and attend regular lectures at the College.
