Comments ... Nearly clouded out for the year while we were catching up on this Summer's drought. Even the Full Moon cycles were cloudy.
... The weather is starting to turn cooler and I'm expecting better skies, but we still need more rain.
... Some slight dark halos around smaller blue stars, a processing error crept in somewhere. Grrr.
