The Chesmont Astronomical Society is a non-profit amateur astronomy club that exists to observe the night sky and to talk about what we have seen. We meet each month off Route 100 between Exton and Pottstown, Pennsylvania, and we observe every dark window and every other chance we can get! Please read our About Us pages for more information.

CAS is a proud member of the Astronomical League.

I don' t think so. novice astronomers , many friends, disappointing to the extent that sold their equipment.

I was EVIL tonight!

Waning Gibbous Moon August 30, 2010 To All: I was feeling the "evil" effects of lunacy, and risked my eyesight tonight observing with Sol Invictus upon 'da Moon! Though I admit, I first did some extended Jovian gymnastics, watching the transit of the GRS followed by Io's shadow transit. The best views tonight were with the 14mm Denkemeir or the 16mm Brandon, using an 80A filter. I also tried a 10mm Ethos, a 12.5mm UO OPS ortho (now rare, for planetary and lunar observing having a custom contrast-enhancing coating), and the 14mm TMB SuperMono.
