Observation Opportunity @ Ryan Observatory

Observation Opportunity
Clear Sky Gathering

Saturday June 21 , 2025

This will be conducted if clear skies are prevalent at sunset.  Check out  our Discord site for updates late Saturday.

Members and registered Volunteers are welcome to set up their own personal gear to observe from the amphitheater of the Ryan Observatory. This opportunity provides a secure dark sky location and practice with your equipment. With good conditions, we can see the Milky Way from the Observatory site.  Binoculars are considered observing gear.

There is no presentation, just fellow amateurs  enjoying the view.  A Rittenhouse representative will be on hand at nightfall to turn of lighting for dark sky and astrophotography observations.  Overnight stays can be accommodated at Muddy Run Campground.  Camping overnight at the observatory is not permitted.
