Before the T9 data came down, I got a little bored, and played around with some Voyager data of Ariel. The mosaic (oft produced) I generated is below. Again, this mosaic has been produced by a number of folks on the net, so this isn't really new, but I thought I would get this product out there anyway. I stretched the image such that only a few crater rims would have a DN=255 (other mosaics boost the contrast a bit too much, overexposing the ejecta around Melusine, for example. I also ran this image through a high pass filter, sharpening the image.
Enjoy! -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Very nice, Jason! I like the extra detail that you get by high pass filtering and not over-stretching it.
A general comment/question about the Uranian satellite images...because of the season, all of the illuminated parts of all of the satellites in all of the images were pretty much in the southern hemisphere, right? Yet it's really rare to see the Uranian satellite images oriented so that the south pole is at the bottom of the images. I usually rotate any such views before I post them to make them hemispheres illuminated from the bottom, assuming that that puts north at the top. Is that right? --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
