I did not use any filters. I had carefully collimated the scope with a Cheshire/sight tube and an autocollimator. I turned on the baffled fan behind the primary. The OTA and focuser are fully flocked with Protostar. I was using a Burgess Binoviewer with a 1.9X OC together with various pairs of eyepieces. The set which gave me the most pleasing views was a pair of Orion ED-2 22mm eyepieces, which yielded 104X, 0.5 TFOV, and 2mm exit pupil. The ED-2s were sharp edge-to-edge and showed excellent color and detail. (Yes, the much-maligned ED-2s! Go figure!)
I began sketching Jupiter at about 6 UT. The sketch is in the inverted orientation. The GRS was red and obvious. A trailing line was on the p side of the GRS. There was much activity in the SEB, which was darker than the last time I observed several weeks ago, but still not as dark as the NEB. The NEB had an obvious white notch toward the N p edge. SEBn was a light blue-grey, and showed a number of wavy formations.
