The York County Astronomical Society (YCAS) will offer a public Starwatch at its observatory at John C. Rudy County Park, 400 Mundis Race Road, York, on Saturday, Aug. 8, from 8 to 10 p.m.

The event will begin with a screened astronomical presentation on current astronomy topics.

Guests will then be guided on a tour of the sky through one of the club's telescopes. Attendees will be shown a host of celestial objects.

While the event is free and open to the public, donations will help the society to continue to bring astronomical events to York County and surrounding areas.

If the weather is clear, all activities will occur as scheduled. In the event of extreme weather, call 717-759-YCAS (9227) for notice of cancellation or visit http://www.astroyork.com or http://www.facebook.com/AstroYork.

Those who own a telescope but are not sure how to use it may schedule a lesson at the observatory by emailing info@astroyork.com.
