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

Meet at the Avalon Barn, click here for directions.

Please join us on Friday, January 24th, at 7:00 pm, we will be showing “Origins of Life” in the Barn.

Click here for more information about this program.

Sky Lab and Sky Dome viewing will begin around 8:00 (weather permitting) and will include Venus, Winter Constellations and various Deep Sky Objects.

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!
