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. Fecker 15" Telescope 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. In 1950 the telescope was purchased by the University of Oregon and placed atop the science building in Eugene until 1961. 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. The positive results from that survey led to the construction of PMO. 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! Unfortunately, by the 1990s the Fecker had fallen into deep disrepair. It was not until 2012 that the Head of Operations Alton Luken (a PMO volunteer at the time) found the telescope under a shelf behind rolls of insulation. Luken spent the next 3 years fully restoring the Fecker to her former glory. 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. Boller & Chivens 24" Telescope 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. In August 1967 the telescope was installed and the grand opening of PMO was held on September 17, 1967. That same night, the telescope saw its first light! Throughout the 1970s and 1980s the Boller & Chivens 24" was active in cutting-edge astronomy research. In fact, in 1970 this telescope made the very first observation of a class of star that would come to be known as magnetars. Since its heyday in the 70's and 80's the Boller & Chivens continues to be one of the most important telescopes at PMO. Currently it is being used for undergraduate research projects, technology development, and for public outreach events. Sigma 32" Telescope The Sigma 32" telescope and its massive dome came to PMO as part of an
