Many of us met along “Main Park Road” at the Play Field parking lot at Tyler State Park. The Lunar Eclipse played out over the course of several hours with a gradual darkening of the Moon starting around 9 PM and a coppery color full eclipse phase beginning a little after 10 PM till 11:20 PM, then the process reversed as Earth’s shadow slid off the Moon bringing back the full illumination. Even though skies were partially overcast, we managed to view many of the phases of the eclipse. Additionally, many were able to capture wonderful photographs, once again demonstrating the enhanced “seeing” of the camera over the eye, especially under adverse conditions.
October 7: Our featured presentation is BLACK HOLES! Kelli C. Spangler MS, Assistant Professor of Physics and Astronomy at Montgomery County Community College, will focus on Black Hole theories of evolution which are going through an evolution of their own. With new data arriving regularly, astronomers have discovered conditions of the early universe that not only challenged theories of black holes but also stellar and galactic evolution. This presentation will review the initial theories of and discuss the new data and theories of black hole evolution to explain inconsistencies that were, until now, unresolvable.
Kelli is a dynamic and engaging presenter; this presentation will certainly be both stimulating and enjoyable!
Kelli is a tenured faculty member at Montgomery County Community College where she has taught Physics and Astronomy for 13 years. She received her BS in Astrophysics from Colgate University and MS in Physics from Drexel University.
Our featured presentation, by Bob Black, from Skies Unlimited, focused on eyepieces and their impact on our visual observing experience. Bob covered fundamentals of eyepiece design and use, drawing on his extensive experience to introduce the concepts of scaled designs (Kelners, Orthos, and Plossls) vs. the more modern proprietary designs and why that matters when selecting and updating your eyepiece collection. There was something for everyone, from beginning to experienced telescope users.
Our meetings beginning at 7:30 pm at Upper Dublin Lutheran Church, 411 Susquehanna Ave., Ambler, 19002. Look for the black and yellow BMA2 signs.

Our featured presentation was given by Valentino Gonzales (LTC USAF- Master Navigator), former director of the Imax Theater and Fels Planetarium-Franklin institute Science Museum. He described how celestial navigation works. It uses angular measurements (sights) between celestial bodies and the visible horizon to locate one’s position on the globe, on land as well as at sea. Val demonstrated different types of sextants and explained how they are used. We also had sharing time for observing highlights, astrophotographs and observing experiences.
All our meetings are open to the public. Meetings beginning at 7:30 pm at Upper Dublin Lutheran Church, 411 Susquehanna Ave., Ambler, 19002. Look for the black and yellow BMA2 signs.
