Clearish again on the morning of August 9th, with some patchy high cloud. Very heavy dewfall was another serious issue.
I decided to image with my William Optics FLT 110, this proved to be a good decision as the seeing was bad - rapid boiling with considerable amplitude. Variable high cloud & mistiness did not help at all.
So, the Moon: (click twice for full size version, annotated with full details)
and Jupiter (with Io sneaking onto the left edge of the frame, and moving fast enough to cause a registration issue in the RGB version. Using straight red for luminance fixes that one!)
Note the brighter background in the blue image: the sky was getting quite bright by this stage. A carefully chosen gamma reduction was used to make this frame balance with the others.
Venus escaped imaging as thickening high/mid level cloud interfered and persisted practically all day.
