Becoming a

MAS Keyholder

Through years of hard work by countless volunteers, fundraising efforts, and with overwhelmingly generous donations, the Minnesota Astronomical Society has some of the finest amateur equipment and facilities available. We are likely one of the best-equipped amateur astronomy clubs in the country, if not the world, maintaining five observing sites, four with observatories, that are available for our membership to use.

Observing Site Amenities

Each site includes observing amenities, ranging from a simple warming structure and concrete pads to a fully-equipped observatory housing multiple telescopes.

Casby Observatory, and HotSpot Classroom became operational and complement the Onan facility. ELO is the main public outreach facility of the MAS with scheduled public star parties from March to November.

Listed below are numerous items that require periodic attention. These items can be done as part of a ”Work Party”, but can also be done by an individual as needed, such as dusting off the equipment, vacuuming, replacing light bulbs, etc. Your help is greatly appreciated in keeping the facility a place we can all be proud of.

  • Open the observatory for member/visitor use during MAS star parties.
  • Help with public events at the observatory either as team member or team leader.
  • Participate in observatory construction “work parties” (pulling weeds, telescope and building maintenance, etc.).
