Eagle Lake Observatory

Consisting of the Onan Observatory, the Sylvia A. Casby Observatory and the HotSpot Classroom, the MAS’ Eagle Lake Observatory is the regions premier all-volunteer public observing facility.

  • Two observatories with more than a dozen of the finest amateur telescopes available to view through.
  • Real-time video viewing capabilities for lunar, planetary and deep-sky viewing.
  • Solar filters allow safe viewing of the Sun’s surface, sunspots and solar prominences.
  • Mounted 15×80 binoculars for the ultimate “wide-field” stargazing experience.
  • A heated classroom to take the chill out of the cool fall nights.
  • Electrical outlets on the outside of the buildings for those who bring their own scopes.
  • Paved handicap parking adjacent to the wheelchair accessible observatory.

Event Cost

There is no charge to attend a public star party. To help us maintain the observatory, purchase door prizes and to pay the bills, donations to the MAS are also welcome.

Astronomy Day

The theme of Astronomy Day is “Bringing Astronomy to the People”. This worldwide event invites astronomical societies, planetariums, museums, and observatories to sponsor public viewing sessions, presentations, workshops, and other activities to increase public awareness about astronomy and our wonderful universe.

Astronomy Day was born in California in 1973. Doug Berger, then president of the Astronomical Association of Northern California, decided that rather than try to entice people to travel long distances to visit observatory open houses, they would set up telescopes closer to where the people were – busy locations – urban locations like street corners, shopping malls, parks, etc.

His strategy paid off. Not only did Astronomy Day go over with a bang, not only did the public find out about the astronomy club, they found out about future observatory open houses. Since the public got a chance to look through a portable telescope, they were hooked. They then wanted to see what went on at the bigger telescopes, so they turned out in droves at the next observatory open house.
