Helena Astronomical Society

The Helena Astronomical Society is the Montana capital’s amateur astronomy club, dedicated to offering free, public educational outreach and special observatory nights for our members.

Regardless of your experience level, if you have an interest in astronomy you are welcome to join us.

HAS owns 2 telescopes. Our 10" Meade SCT is mounted on our dedicated pier at the Montana Learning Center on Canyon Ferry Lake and our "lending" telescope--a 6" Dobsonian reflector--that can be checked out by members.

Additionally, we have a good collection of books on astronomy for all interests and skills that are available through a lending library.

See our Meetings page for more details on our regular monthly meetings.
