Seeing was not good and details were not clear.

Dear sirs,here are my multi spectral Jupiter observations from Sept 23,with frequent periods of good seeing.
Numerous details are seen and was a good opportunity to collect data to replicate,with better quality images,
the image ratio and image subtraction experiments I started last apparition.
As you well know,the two broadband IR filters used (>685nm and >850nm) are enriched in continuum,the Sloan z'-s'
and Y' band filters (each one with a 100nm band pass) encompass the strong (890nm)
and weak (1000nm) Methane absorption bands,respectively,which are detected by dedicated filters (890/20nm and 1000/20nm).
In the included image sets I focused my attention to WS6 (labeled on enhanced insets of right images)
and a very small mid EZ outbreak (labeled on left images; it was close to CM).
WS6 appears to be resolved in various subdomains,from which only the S one is dark with the strong CH4 band filter (as expected from a cyclonic feature).
This component is already bright with the weak CH4 filter (which would probe deeper into the atmosphere),
and all components are bright in broadband IR and in the visible.
It is curious that in RGB,the small S component appears redder.
With respect to the small mid EZ outbreak,it is readily visible with all filters
with the exception of the strong CH4 filter (it is however well seen with the weak CH4 filter).
Thus it should not be a very high atmospheric phenomenon.
