WHAT IS PUBLIC OBSERVING?

The York County Astronomical Society holds a public observing session every month, check this website for times. 

The club's telescopes will be used to show the public many of the fascinating objects that are up in the nighttime sky. We will also be showing people how to use Star charts to identify the stars and constellations that are up in the nighttime sky. The public is encouraged to bring their own telescopes, if they have one, to learn how to use them more effectively. If you are interested in buying a telescope, this is a great place to ask questions.
