Our public observing session planned for tonight Sunday, September 18th will proceed as planned. Skies should be mostly clear but we will have the haze from western wildfires to deal with, but hopefully we will be able to see some objects through the telescopes. Gates for the public will open at 730pm. When arriving on the observatory grounds, please be sure to leave your headlights on until you are parked for the safety of everyone in the parking area.


The Next General Meeting of the Astronomical Society will be held on Monday October 10th at 730pm. The meeting will be held online via Zoom. Zoom invites to the meeting will be sent to members closer to the day of the meeting. Any non member wishing to attend can contact president@astrohbg.org to get a Zoom invite for the meeting. See our meeting page for more information.

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.
