A recent R-RGB re-evaluation of Jupiter data from 2012 December 12 taken with my 10" Newton and 5.2 µm ALccd5 camera at f/13 uncover image detail not seen on simultaneous 14" and 16" images by Christopher Go and Marco Guidi taken at the same time under "excellent" resp. "very good" seeing conditions.
See in particular tiny double line above northern cloud band. I suspect too long focal adaptation and single frame exposure times in case of the larger telescopes.
