[Moderator's note: This thread contains images from the Iapetus 2007-09-10 flyby and discussion of them. It was created by splitting this thread which contains pre-flyby discussion]
Another CL-UV3-GRN-IR1 set was posted today, though Iapetus seems to have been hiding from the green and IR filters...here's my best effort at making something from the CL and UV3 images. Lots of topography on the limb! --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Great stuff! Sadly the sole long-wavelength image seems to have missed, so I had to fudge for the red channel. The version below consists of clear for red, a stack of four green images for the green (clear plus 3 polarizers), and, for blue, the UV3 channel with cosmic ray hits erased or corrected for by copying bits from the polarized channels where cosmic rays hit the sunlit part of Iapetus. Then I converted to Lab, replaced the lightness with the clear image, and went back to RGB.
That's some pretty rumply looking topography in the southern hemisphere basin! The "belly band" seems to look sorta segmented, with little north-south notches cut into it. --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
