The Haggart Observatory at CCC

The Haggart Observatory is located at Clackamas Community College's Environmental Learning Center on the Oregon City campus. It originally opened in 1989, and as with many projects at the college, its construction was the result of strong community support, including donated and repurposed materials, financial contributions and countless volunteer hours. Learn about our history.

Through a valued partnership with Rose City Astronomers (RCA), a local amateur astronomy club, we are able to provide viewing opportunities for the public several times a year. Attendees get to observe the night sky through a beautiful 24-inch Newtonian reflector telescope, located in the observatory dome, as well as through several portable telescopes that are placed on the observatory deck. RCA volunteers guide stargazers and ensure that everyone gets to see a sampling of objects that are viewable on that particular date. Learn about our telescopes.

Public Viewings

We are thrilled to announce the reopening of the observatory and welcome back public viewing opportunities in 2023! This year, we're focusing on Earth's closest neighbor, the moon. While you can look up any day or night and have a 50% chance of seeing it (weather permitting), have you seen it in detail through a telescope?
