The AAAP Observatory at Washington Crossing State Park is currently closed to the public due to COVID-19. Re-opening plans are being developed.

Please check this website for future change in status. We will also broadcast on Twitter and inform our members via email with any reopening plans.
One of the purposes of the AAAP is to educate the public about the wonders of the universe over our heads through our lecture series and outreach program.

Our astronomers setup telescopes for public use at Communiversity in Princeton, Super Science Saturday at the NJ State Museum in Trenton and at various public events around Mercer County.

We will bring telescopes to your school or educational event to show and explain objects in the night sky like the Moon, constellations, planets, nebulae and galaxies.

Come visit the Universe at our state-of-the-art astronomical observatory located near Pennington, NJ just minutes from I-95.

AAAP astronomers will show you galaxies, planets, ghostly nebulae, spectacular globular clusters and jewel-box, open star clusters. Using our research-grade Celestron 14-inch Schmidt-Cassegrain telescope mounted on a Paramount Robotic Mount and our historic 6.25-inch Hasting-Byrne refractor scope. You will see the night sky like never before.

We've installed a video camera so everyone can see astronomical objects on an LCD screen. View deep sky objects on a large LCD screen.

Sidereal Times is the official newsletter of AAAP since 1962.

Published in blog form now, it is the best source of current news about club activities. In addition, we publish essays, gear evaluations, astrophotographs, book and movie reviews, poetry, travelogues and technical articles related to our hobby.

AAAP plans to post on this website soon our archive of all issues going back to the club's founding. We hope to complete this project soon.
