I was out observing with the SW 80ED from about 9.30 to 10.30 pm.  Best views were with the binoviewer, x3 barlow and x2 24mm Orthos.  Excellent details particularly of the interior of Janssen.  Janssen is a fine approximately 120 miles walled plain which has slopes interrupted by numerous more recent craterlets with it's N wall impacted by Fabricus and Metius.  Its interior is full of fine detail including hills, craterlets and rilles, the longest being approximately 84 miles long running N to S. The seeing was much better than I expected in the very humid and warm evening.  Attached is a single frame of the disk and a crop from it to show Janssen and its surroundings.  The images do not do justice to the wealth of detail available with visual observations.
