[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.

I tried stacking 6 of the most recent images in RegiStax. They were obtained at a range of ~490,000 km. I omitted the polarized UV images as they looked too noisy and fuzzy.
This version has been sharpened with wavelet processing followed by postprocessing in Photoshop (mainly brightening it slightly). Probably overprocessed, doesn't look as nice as Deception's version above: The following version has been processed to reveal the nightside. As these are not long-exposure images and the JPG compression destroys dark, low contrast details not even large scale features are visible on the nightside. However, Iapetus' entire limb is apparent and the irregular terminator looks nice: |
