Clear Sky Gathering ONLY
May 10 , 2025

This is a private gathering for Members, which include Observatory Volunteers. Membership should be current.  It can be renewed on site if necessary via PayPal, credit card or on site with personal check. 

Observatory parking areas and visitor center are closed, alternate parking provided at upper parking lot North of the Observatory.  You may set up your personal gear to observe from the upper lot, campground bathroom is available at West end of lot.  You may also bring your observing gear down to the amphitheater.

For members interested in volunteering this summer at the observatory, we will conduct a Dome 1 orientation at 8:45 PM.  It will give you a good idea of what is involved if you want to operate an observatory for open houses.  Other opportunities to get involved as an educator or general site assistant will be discussed.  If clear, we can also practice laser sighting constellations.

  Conducted by Rittenhouse Astronomical Society.

Bring your own personal gear to observe.

A Rittenhouse Representative will be on site at Astronomical Twilight to turn of lighting for deep sky observation and photography.
