This page lists the detailed specifications of hardware and software used in the Calvin Observatory (on campus in Michigan) and the Calvin-Rehoboth Observatory (near Gallup, New Mexico). The two observatories are designed to be very similar in equipment. The local site is used for hands-on training, equipment testing, and nighttime viewing by students and visitors. The remote site is operated robotically via the internet and gathers high-quality data every clear night for class projects and research.
