John,

this color composition is presumably misleading, since the individual grayscale images are NOT calibrated! Unlike the mission people, you don't have the respective hardware information, I suppose...

The Dione image looks far too bright. See my thread in CM:


My Dione color is based on this officially released natural color RGB composite...

This is the result from GIMP-coloration with this color template.

See the inlay photo illustrating the striking difference in albedo of Enceladus and Dione.

they are just "quick"

two quick rgb composite images... it is 12:30 am so I'll do some more digging tomorrow

composite images, i only took about 30 min to do both

John,

it's not a matter of the amount of time you are spending on processing composite RAW images. It's the calibration that you presumably don't know, no matter how much time you spend. The only chance might be via ISIS3...

But there are good-looking officially released natural color images both of Dione and Iapetus. So why taking the risk of a hidden miscalibration. At least, via the "official track", one has a clear trace and documentation to official sources. Then NASA must take responsability and the texture visualization in Celestia satisfies scientific standards.
