...on the spectral artifacting in that image. Now that you mention it, it reminds me a whole lot of one of my favorite Cassini images at:
...containing the image of Saturn and the ring plane with "opposition glow" off the rings at
...which is an approximate composite natural-color view shot in three rapid-fire exposures through red, green, and blue filters as the spacecraft pulled away; everything is "in register" except for the opposition glow which, because the spacecraft was travelling so fast, was exposed in three slightly different positions, creating a spectral artifact which wouldn't be visible to the hypothetical human passenger aboard Cassini.
