Public Viewing

The Observatory welcomes public interest and highly promotes the field of astronomy to those who are interested. Our public viewing program runs all year round and is popular with the local and visiting communities. On public viewing nights, visitors are able to observe selected celestial objects in the presence of friendly staff, in addition to engaging in various on-hand presentations. The observatory is open regardless of weather conditions, even though viewing through the telescope is limited to clear skies. If it's cloudy, drop in for a slide show, a planetarium show, and a tour featuring both of our telescopes.

Visits to the Observatory are free. However, donations are kindly appreciated. See one of the staff if you wish to make a donation.
