Ian's image is orientated with North up. But iff you rotate my image to also orientate North up you can see the hi-res detail in Ians image in this region coming from oval BA. What is appearing in my data as a diagonal structure is resolved into discrete detail in Ian's image.
The difference between the two data sets is a reflection on the difference in altitude of Jupiter, nice and high in Spain and the difference in the quality of the seeing.
Reckon the ring opening relative to Earth, approaching its max really is quite significant. This is the first time in about 30 years we will get such a good look at the North Pole and the majesty of this side of the rings wide open. With the ever increasing quality of cameras for planetary imaging. just how good is this going to be.
To see the image of Ian Sharps I referred to above go to the PVOL link.

Put your two images side by side as you suggested with the same orientation and yep the
Canali 
seem to have dissipated in Ian's image, as you say, that's seeing for you. His name is rather poignant too huh?
Is that a standard C11 he is using? Wow SCT's can get a bad rap re image quality at times but ironically seem to produce many of the great planetary images, go figure
