HI Robert,

Ah yes, there is solace in someone who understand your plight. Finding new interest in the MOC wide angle photos, namely atmosphere and the presence thereof. I'm thinking this is a fairly accurate color rendition of Mars. The green layer is modulated a little bit whereas green does not necessarily fall in the middle of blue and red. Overlying the layers is as difficult as you suggest. A stretching plug-in would help quite a bit but I've searched high and low.
Below are some links to some more photos if you enjoy them, remember, I couldn't have done them with out yah.
