No problem. Here's the url's to the 2 images I've used for this moon test.tgd...

http://rockyknuckles.googlepages.com/moonfull_luminosity.jpgYou could just use one map but I have edited the image to use in the luminosity channel to apply more white at the bright spots.
Huge displacement is added with the main image-map(500,000m), this is really high but it is just to give some texture from this distance away. Just make sure you lower the displacement in the default shader if you shrink the moon planet.
And, if you do shrink the moon, you'll also have to resize the images in the image-map shaders. So far I've had no luck with spherical or object UV mapping, I just use through camera and line it up with the planet's edges with the image-map shader transform controls.
The easiest way I find to do this is to set each map to 'position centre' and because the moon is bang on centre in this render view I use co-ords: x=0.5 y=0.5 and resize relatively until the face of the new planet is covered correctly, in this case I needed size 0.425 in both boxes(because the image is projected through the render camera you don't need different sizes to match aspect ratios).
You can have your moon anywhere, not just centred, you just need to change the sizes and co-ords of the maps to fit.
