With the support of David Patterson, the University South Foundation constructed the Patterson Observatory to offer the community a place to observe the night skies in Cochise County. The Observatory houses a Ritchey-Chretien telescope of 20” aperture. This telescope, with its sophisticated detectors, is capable of observing objects one million times fainter than the human eye can detect. In 2019 the Foundation completed a remodel to include a kitchenette and bathrooms adjacent to the Patterson Classroom.
School field trips and monthly Public Viewing nights open up the Patterson Observatory on a regular basis.
