All of our meetings are open to the public.

Wednesday, August 5: Our featured presentation, by Valentino Gonzales (LTC USAF- Master Navigator), former director of the Imax Theater and Fels Planetarium-Franklin institute Science Museum, will deal with celestial navigation; how does it work? Celestial navigation is the use of 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 will demonstrate two different types of sextants and explain how they are used. We will also have sharing time for observing highlights, astrophotographs and observing experiences.

The public is welcome at 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.
