I reprocessed the integrated light Saturn image from Oct 13th for a more
'natural. appearance. What struck me immediately is the presence of the
Keeler gap. I compared the image to Maurizio's Sep 2 shot, and a recent
image by Ed Grafton (both showing the division.) and it is located at
exactly the same place in Ring A. The image is composed of 30 individual
images, so it certainly isnt an artefact!. I also attach an LRGB using the
integrated light image as L component.
