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?

Oh baby! The equatorial section in the image is the part of Titan I've been really waiting to see!

Lookit all them complex cool-o shapes!

Meh, we've seen this area before at higher resolution last year wink.gif

I'll be looking for Kraken Mare in a bit, I'll let you know if I find it. Keep in mind that it is pretty close to the terminator AND the limb up there, so it may not be visible in those compressed, 8-bit jpegs.

This is the most I can get out of the terminator region:

It holds promise for the original raw data.

Thanks Gordan. I think I can make a couple of dubious identifications of the shoreline there but too uncertain to be worth noting. I look forward to the professional version VP.

That dark region to the north still looks like it's darker than it should be.

Odd.

The simulated view in 'looking ahead' shows that the follow-up images from 21st September are from a better angle for lake viewing. Not yet on the raw image page last time I looked, but I'm keeping fingers crossed.

Gordan, now we have the images from 21-22 September with the lake showing clearly would there be any chance of a commparison image to set beside your last one in post 4? I want to try viewing both as 3D and see if Kraken Mare matches any faint features on the 20 September view.

There'd be no use in 3D as the moon rotates in addition to the phase angle changing. I forgot the exact procedure I used on the Sep 20th images so can't repeat it, but here's a (better IMO) shot at the Sep 22th images:

September 25, very low phase:

Nice - thanks. It's clear from the 20/22 comparison that the two rightmost extremities of Kraken Mare are (just) discernible in the earlier view. You'd be surprised at what I try to do cross-eye 3D with sometimes blink.gif but you're right, that pair is giving me too much of a headache.

I had just about given up hope for seeing clouds, but there they are. These seem to be in the same 56 deg. North range as other streak clouds seen in the north.

Ugordan, excellent work. What might be neat is to merge these images with color images (in other words, color data from true or close to true color imaging with a grayscale that is a mix of these processed images and the grayscale data from the color image. It wouldn't be "true," but it would give it a Titan-ish feel).

I wonder if you could clarify something for me? Ciclops 'looking ahead' for rev 85 mentioned looking for changes at Kraken Mare. Did that mean clouds, or something else?
