ASH's Public Observing Sessions

ASH's has public observing sessions planned during the warmer weather months where we open our observatory up for the public to view objects through our telescopes! Please see the public observing page for dates and times! . The Public Observing sessions are held at ASH's Naylor Observatory located at 670 Observatory Drive in Lewisberry PA. The public is able to view celestial objects through telescopes located in multiple observatory buildings. Also be sure to see our meteor collection located in the Asper Building! We can only hold the events when the sky is clear enough to use the telescopes, so if it is cloudy or raining we will have to cancel the session. If we are forced to cancel a session, we will announce it on this website, on the Naylor Observatory Facebook page, or you can call the observatory at 717-938-6041 30 minutes before sunset on the day of the session to see if it is cancelled.

We invite you and your family to visit Naylor Observatory on selected evenings this year. Come and observe the beauty of the moon, planets, double stars, star clusters, nebulae and galaxies with your own eyes through our large telescopes. Admission is free.
