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.
