The Avalon Sky Lab

Led by David Cohn and David Barnett

Our innovative observatory structures reveal the sky for both stellar and solar observing.

Meet at the Avalon Barn, click here for directions.

Stay tuned for our next event

The Avalon Observatories house several permanently mounted telescopes and are used in conjunction with educational programs here at Avalon. These include observing and imaging a variety of celestial objects and events including sunspots and solar flares.

Our monthly programs have included the use of a portable planetarium in all weather conditions, and have featured a variety of portable telescopes on clear nights. The permanent Avalon Observatory enclosures allow us to make telescopes available on a moment’s notice and help us provide more frequent viewing opportunities. Stay tuned for even more frequent events!
