[1] PMO supports a wide variety of programs with an emphasis on projects that allow undergraduate students to be involved with many aspects of facility operations.

The site was discovered and characterized by professors Russ Donnelly and E.G. Ebbinghausen in 1965 when they determined that the sky conditions were excellent and worthy of an observatory being built on Pine Mountain.

This telescope, named 'the Robbins' after contributor Kenneth C. Robins, will soon be operated from locations far from PMO by students and researchers from UO and other educational institutions.

Even though this 14" telescope is smaller than the others at PMO, it is one of the most powerful instruments at the observatory due to its start-of-the-art optics, electronics, and camera system.

PMO scientists routinely use the Robbins to observe a myriad of astronomical targets, from nearby asteroids and comets to clusters of galaxies.

The Fecker 15” Cassegrain telescope is often referred to as the “Matriarch of the Mountain” because of its long, rich history and importance in the development of PMO.

At that time Dr. E.G. Ebenhausen of the physics department took the Fecker to Cache Mountain near Sisters, Oregon to conduct an atmospheric feasibility study.

In the earliest days of PMO the Observatory received a grant to construct a dome for the Fecker, and the 'Grand Old Lady' saw its first light in the spring of 1968!

The telescope was then re-installed in a dome in summer 2015 and the Fecker has acted as an invaluable tool for UO Physics students to develop their science communication skills and for the public to learn more about the universe.

Completed in summer 1967, the Boller & Chivens 24” dome was the first building constructed at PMO after a special use permit from the Deschutes National Forest was granted.

Due to the unique nature of the telescope design (among only 5 ever built) it has not been possible to repair or replace the custom parts required to bring it back into operation.
