We offer free public shows every week or so during the school year. Because the planetarium can comfortably seat only 25 adults we have a ticketing system, although the tickets are free. The tickets are free, but we do accept voluntary donations to help defray costs and purchase new shows.
If you have a group of about 25 people you may want to simply schedule a private show, and you can choose which show you see.
Be sure to check the Frequently Asked Questions about attending the planetarium before you arrive.
