Decided to hunt down different views of Tethys recorded by Cassini in UV, G, and IR. Here are three previous passes. I have no idea which way is up, though I believe the right image is looking almost strait down the north pole.

Yes, and the other two are looking at the south pole.

for "UV, G, and IR." to blue.green,red ( well RGB)
what percent's did you use ?
in the past i have found ( depending on WHAT UV and IR filter it used - near or far ) that i need to add aprox. 20 to 35 % of the green image into the UV and IR images

Here is an RGB image mosaic that was taken Oct 28, 2004. This may help in adjusting IR/G/UV images. Perhaps a reduction in saturation of around 50% would work to convert the more enhanced looking ones?

Thanks guys. Here's a revision with 20% of the green added to both UV and IR channels. Less saturation too.
Click to view attachment the IR and UV amages are only near (UV3/IR3, I think).
