Again, regarding this image...

Yes, checking.. it is the Encke Gap... I was so calm
and sure about what it could be last night, since the
images are not labelled in the press release,
but now that image has sunk into my brain.
I must say :
WOW !! THIS IMAGE IS ** AMAZING ** !!!!!!!!!!!!!!!
I am accustomed to seeing the Encke Gap in images only a few pixels
wide (from Voyager mostly), and now I'm in awe. I'll bet
Mark Showalter is bouncing off the ceiling with that image.
( and this is only the *beginning* of the orbit tour !)
