Volunteers, Members and their guests and interested Amateurs (from any astronomy group or society, or those interested in membership) are welcome to set up their own personal gear to observe from the amphitheater of the Ryan Observatory. This opportunity provides members with a secure dark sky location to conduct your personal Messier Marathon with your equipment. With good conditions, we can see the Milky Way from the Observatory site.  Observatories will be open dependent on volunteers. Visitor center is not open other than bathroom use.  

This is also a good time for our volunteers to grow their observatory ‘situational awareness.”  Time operating the telescopes is excellent practice to grow ones skill set.  Volunteers can learn tips from each other.  There is no planned programming, no speakers, just members and volunteers using their own gear.

A Rittenhouse Representative will be on site to track attendance and dim lights at Civil Dusk for dark sky observation and photography.

NO sleeping is permitted in personal vehicles at the observatory. Muddy Run Campground is closed for the season.

Dr. Nunn offers an introductory presentation on astrophotography, guiding enthusiasts from the most basic setup to building a dedicated astronomy rig. The presentation covers key aspects such as techniques, software, hardware and time management. Designed to be accessible for beginners, the session also offers pathways to more advanced techniques and equipment for those looking to deepen their knowledge of astrophotography.

It’s looking at this point to be a clear night. Although the meeting presentations end at 8:30, we will leave the Zoom link live on the dome telesccope. Nightfall is not till after 10:00 PM. When light allows, we will share some views that one might see on a “Star Survey” at the observatory. We are always searching for new members interested in becoming observatory operators, consider this an opportunity to see in person what it’s all about.
