Blue Mountain Observatory Open House

  • Where: Blue Mountain Observatory Forest Rd 19247 Lolo, MT
  • When: Sep 18th, 2026 at 8:30pm

Join UM astronomers and Western Montana Astronomical Association (WMAA) members at the Blue Mountain Observatory this summer for our stargazing nights. In addition to our 16-inch telescope, our volunteer astronomers and student staff will have a variety of telescopes set up outside the dome and will be happy to discuss any questions you may have about astronomical instrumentation. They are available to talk about what you are seeing through the telescopes, discuss current discoveries, point out constellations, share star stories from different cultures, and demonstrate how to find interesting celestial objects with the unaided eye or a pair of binoculars. (It's fun to bring binoculars if you have them.)

Public Observing nights are ticketed events, and attendance is capped at 75 people.

A sunset stroll along the Riverfront Trail is never a bad idea!
