A description about eye anatomy and visual observing will answer questions about why we need to dark adapt, why we don’t see colors when observing and, if you wear glasses, is it necessary to wear them when observing.
Star Charts: an historical perspective by a former director of LVAAS. He’s been studying and collecting antique star charts and atlases for 30 years. He will take us on a journey from the dawn of printing in the 15th century to modern times, showing us how maps of the heavens have evolved and how the art and science of celestial cartography progressed through the centuries.
Our meetings starting at 7:30 pm, are open to the public, and held at Upper Dublin Lutheran Church, 411 Susquehanna Road, Ambler, PA, 19002.

Bring your own binoculars to compare how they measure up any star charts you might use.Following the star hopping presentation, we will have “show and tell:”
