Image set from yesterday afternoon,again with the session starting in bright sky well before sunset.

Its unusual to be ending an imaging session as the sky darkens,but that’s the situation with Jupiter at present.
Note: There is a reddish darkening in the RGB in the NPR,
which I attribute to a slight blemish on the camera cover glass which is exacerbated under these bright imaging conditions.

Dear sirs,here are yesterday's Jupiter images,all obtained before the sky was completely dark.
Thus,filter calibration for subsequent subtraction / ratio is virtually impossible.
Anyway,I added a gif animation between CH4 727 and continuum 750.
Differences in polar regions,in belt/zone contrast,and in small scale clouds mainly located at EZ-EB (N and S) interfaces,are still seen.
A large NEB barge is near CM.
