DPAS operates and maintains the Leif Everson Observatory. This is equipped with a 16” Ritchey Chretien Telescope, with an 8 inch Maksutov piggybacked on the big telescope on a state-of-the-art robotic mount, a weather station and a budding project in radio astronomy. On a portable mount is a 102mm refractor with a hydrogen alpha filter for studying details of activity on the sun.  DPAS also has a portable planetarium with a state of the art computer projection system which is used 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.
