DPAS operates and maintains the Leif Everson Observatory. This is equipped with a PlaneWave Instruments 17 inch f/6.8 Corrected Dall-Kirkham Astrograph telescope on a state-of-the-art L-500 mount that provides exceptional optical and tracking performance for astrophotography, or research. On a portable mount is a 102mm refractor with a hydrogen alpha filter for studying details of activity on the sun.  DPAS also owns and operates a portable planetarium with a state-of-the-art computer projection system which is used on cloudy nights, daytime activities and for public outreach in local schools and libraries.

The Star Garden at the observatory is used for viewing the sky with unaided vision, binoculars and members’ telescopes. There are also binocular mounts set in concrete which allow people of various heights to share the same view.
