I'm trying to model Pluto's moon Charon in TG2, basing it on Neptune's moon Triton as seen in this Voyager photo:

I've thought of using a stretched power fractal, but I'm not sure if that will work. Any help would be appreciated.
See what you can do with this. Unfortunately, the streaks would best be served using a unidirectional procedural blur noise a top the highest peaks in which case is either technically impossible or just has not been thought of.
I would try an image map. You would get very good control of the look this way.
Nice, ChrisC. Only problem is my Charon model has a radius of 593 km, not 6378 km like Earth, and mine's more blue than red. The red version might work for Pluto, though. :D

Easily adjustable i would imagine. I also noticed that there are some distinct structures along the surface, however some new fractal types would have to be made for some.
You mean the wrinkles on the surface? I tried using glen5700's Fractalized Voronoi with negative displacement. I haven't looked at it up close yet, so I'm not really sure if the negative Voronoi works.
I looked and it chews up the planet with insane displacement. I had to remove it and opt for a PF node which doesn't quite give me what I want. :(

I don't think you are going to get what you want, at least not this way. Try an image map like what njeneb suggested and just layer paint a load of imagery in your photo editor as part of the alternative. Simply put, the fractal functions are not there. That moon has very distinct patterns along it's surface.
I had found a map here. See if segments of it might help.
