Come out to AAAP's Simpson Observatory on any clear Friday night from April through the end October to enjoy an evening under the stars. We are open from sunset to 11:00 PM.

Our expert astronomers will guide you and answer all your astronomy questions.
The observatory is located in Washington Crossing State Park in Titusville, NJ. It is open only when the twilight sky is clear. To verify that the observatory will be open, please call the observatory at 609-737-2575 on Friday evenings or check our Twitter page for the current status.

We have only a few rules for vistors:
The observatory houses a 6.25-inch, f/15 vintage Hastings-Byrne achromatic refractor, and a 14-inch, research-grade, Celestron f/11 Schmidt-Cassegrain reflector. Both scopes are mounted on Bisque Paramount MEs, a completely automated control system that allows our operators to accurately point the telescopes at any celestial object includng the moon, planets, binary stars, nebulae, star clusters and galaxies.
In 2015, the club added a 5-inch Explorer apochromatic refractor with a Mallincam video camera to the Celestron scope. The color image from the camera is displayed on a computer monitor in the observatory.
The observatory building is a slide-roof design constructed by our members in 1978. It allows optimal viewing of the sky in any direction. Come early and watch us roll off the roof.
