Impressive that you were able to get that much surface detail from Voyager data

Do I recall this correctly: it's only after Cassini had a look at Titan up close that people went back to Voyager data to see if the surface features were detectable? And they were.

I know that Cassini's red filter could also faintly see through the haze, if you cranked the contrast way up.

The principle is right - it was after Hubble imaged the surface. Before that, there was no way to know if these features represented the surface or clouds.

What did you do, Ted? IIRC Voyager 1 didn't see jack. This certainly looks much better than anything I remember from the time.

After seeing a paper on it, I imitated the methodology, then merged results with OGV color/grayscale data about the same time. https://www.sciencedirect.com/science/article/abs/pii/S0019103504000958?via%3Dihub#preview-section-introduction
