Took a long look at comet Lee. The comet is around magnitude 8.5 and condensation is around 3 with the coma around 3 arc minutes in diameter. At times of steady seeing, the nucleus becomes very faintly stellar in appearance raising the condensation a bit. The coma mixes with a very diffuse anti-solar tail. An anti-tail, several arc minutes long, is visible and even more so with averted vision. This anti-tail has a central thread that is visible with diffuseness on each side. It somewhat resembles a slender feather.

Skies were clear with some high altitude stuff near the horizon. 10 Pleiades were visible very near the zenith without deep adaptation.

Did some wide field CCD imaging of the Cygnus area just north of the North American nebula using a 55mm Pentax f/1.8 lens. Image is a mosaic made up of 4 images. Each mosaic image itsself is an integration of five 5 second images.
