Black Forest Star Party

September 23 - September 25


The Black Forest Star Party (BFSP) is an annual dark-sky amateur astronomy observing event hosted by the Central Pennsylvania Observers (CPO). Held every year since 1999, the BFSP generally spans a weekend in the late summer or early fall in Cherry Springs State Park in Potter County, Pennsylvania.

Cherry Springs State Park is one of the darkest sites in the state of Pennsylvania and has been designated as Pennsylvania’s first Dark Sky Park by the PA Department of Conservation and Natural Resources (DCNR). The amateur astronomers who have attended the BFSP can testify that the skies can be great!

The Cherry Springs site is also in a large field, at an altitude of 2300 feet above sea level. This makes for one great place to have a star party!

Cherry Springs is becoming a very popular place! Many amateur astronomers are holding impromptu or organized events here during the observing season. If you would like more information on Cherry Springs you may visit Thom Bemus’ Web page on the Park.

Attendance is by pre-registration only. No registrations are accepted at the event.

The star party is a rain or shine event, so it will not be rescheduled and no refunds are offered.

The star party entry fee is $40 per adult (18 and older). Children under 18 are free, when accompanied by a paying adult. We ask that any children attending be listed on registration forms.

-The entry fee covers camping (tents, campers, RVs, etc.) on the astronomy field for Friday and Saturday night of the star party and access to all event programming. You may arrive before and/or stay after the star party, but will need to pay the nightly park fee. If you do arrive before Friday at noon, please check-in at the registration tent.

-Please note, registration for star party vendors is handled through the vendor coordinator, not this page.  Previous vendors will be contacted directly. If you are interested in being a vendor, speaker, or want to recommend a vendor or speaker, please send an email to blackforeststarparty@gmail.com


Registration will remain open until September 7th, or until we reach capacity, whichever comes first.

Please allow 7-10 days to receive your email confirmation.
