Enthusiasm for observational astronomy, curiosity about cosmology, achievements with CCD imaging and technology. These and all other aspects of astronomy are interests shared by members of the Amateur Astronomers Association of Princeton. The club is based in Princeton, (Mercer County) New Jersey.
This organization of 100 + promotes astronomy-related activities for members and non-members, novice to expert. A wide spectrum of astronomy interests are explored at the AAAP through regular meetings, workshops, use of the two club observatories, public outreach and regional star parties.
Come explore our web site. Here you'll find details about our organization's meetings, discussion topics, members and their scopes, and a lot more. Our organization maintains two observatories: the larger in Washington Crossing State Park (housing a research-grade 355mm Schmidt-Cassegrain catadioptric and historic 159mm Hastings-Byrne refractor). A second facility is found at Jenny Jump State Park in northwestern New Jersey. This houses a 318mm custom-built Newtonian reflector.

Each Friday Evening -- Weather Permitting
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" Schmidt-Cassegrain OTA mounted on a Paramount Robotic Mount and historic 6.25" Hasting-Byrne refractor, you'll see the night sky like never before.
** New for 2015! ---> We've installed a Mallincam Astronomical Video Imaging System. View deep sky objects on a large LCD screen.

Public Lecture: Measuring and Modeling Variability in Quasars and Blazars
September 8, 2015 at 7:30 PM, Peyton Hall, Ivy Lane, Princeton Campus
The first talk of the 2015-2016 season is entitled Measuring and Modeling Variability in Quasars and Blazars by Dr. Paul J. Witta of the Department of Physics of The College of New Jersey.
Dr. Wittas talk will be about active galactic nuclei, including quasars, which are extraordinarily powerful, emitting up to thousands of times as much energy as all the stars in their host galaxies. A minority of them also eject relativistic jets of plasma that form giant radio lobes. All active galactic nuclei are characterized by variability and blazars exhibit the strongest fluctuations. This enhanced variability is due to Doppler boosting of the flux emitted by relativistic jets that point close to our line of sight. We have been measuring variability of quasars and blazars in the optical band from various ground-based telescopes for the past 20 years and have more recently employed the Kepler satellite as well as various X-ray telescopes to gather dense, uniformly spaced data. After setting the context, he will present some of these results, as well as our numerical simulations of variations of radio flux from the turbulent regions behind shocks in the jets.
Dr. Wiita received his PhD in Physics from Princeton in 1976 for producing the first numerical models of radio galaxies. He did post-docs at the Universities of Chicago and Cambridge. He was on the faculty at UPenn and Georgia State University and has been Chair of the Physics Department at TCNJ since 2010. He has been a visiting professor at the Tata Institute for Fundamental Research, the Indian Institute of Astrophysics and Princeton. His research has mostly been in extragalactic astronomy, with a focus on radio loud active galaxies.Don't miss this exciting presentation describing some of the more cutting edge, dynamic research currently occuring in the astrophysics community.
A members-only, meet-the-speaker dinner will begin at 6:00 PM at Winberie's Restaurant. Members, please RSVP via email to email@example.com for a reservation.
Peyton Hall is home to the Department of Astrophysical Sciences, and is located just east of Washington Road, adjacent to Palmer Stadium, on the Princeton University campus.
September 11-13, 2015, HOPE CONFERENCE CENTER, HOPE, NJ
This years event will continue
the simplifying trend of recent years with a focus on observing and
socializing, and with significantly lower costs for attendees.
Bring your own observing equipment or meander between the telescopes of
others in the group who will be happy to share their views of the sky
with you. Bill Murray will be creating a Deep Sky Challenge for
those desiring to participate.
STAR PICNIC AND ASTRO EQUIPMENT AUCTION
OCTOBER 18, 2015, 3:00 PM, WASHINGTON-CROSSING PARK NATURE CENTER PAVILLION
(RAIN DATE: OCTOBER 25, 2015)
Cookout picnic at the pavilion with fun food and drinks and camaraderie with AAAP members and families.
Silent auction of telescopes, mounts, eyepieces and other astronomy equipment acquired by the club over the past few years. This is an opportunity to acquire astro equipment at incredibly low prices.
Observing at the AAAP's observatory if skies permit (note: sunset at 6:15 PM)
