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.
