Kraken Mare should be near the extreme right of this image. I've been staring at it pretty hard but can't be sure I'm seeing anything. Can anybody find a way to pull the lake out of these latest images?

It's really subtle, but I tried to enhance two effects I've suspected from an earlier image.

* a brighter ring extending inwards a few hundred km around the large mare. (lake effect fog or frost condensing out and bringing down bright schizzle deposits?)
* that north temperate black stain is much darker than it should be (compare to equatorial zone at same distance from limb).

I inverted ugordan's image and enhanced contrast. So the bright ring looks dark, and the black stain is white.

(The calibrated product will be very interesting...but this is really neat to think about for now.)
