Welcome to the Chesterfield Astronomical Society website.

Where Are We? (See Location Map in the 'About CAS 'section)

 The Barnett Observatory is located at the end of Hastings Close, Newbold, Chesterfield, Derbyshire. S41 8RH.

When We Are Open

We are open every Friday from 20:00 onward. The observatory usually closes when the last member leaves which will depend upon the weather conditions, what is visible and personal commitments.

Non-members are welcome to come and have a look around before you decide if you would like to join or not.

Group Visits

Group visits (within or outside the normal open hours) are usually available, for more information please click here to send an email to the events officer. Or call 07535865621 for the Observatory Helpline

Some of our members also give talks to local groups about the observatory, general astronomy and other more specific topics.
