In alien beach (Bill Pragnell, 21-11-2005) described the way to make a nice
moon in the sky.
I tried that successfully, until I tried to use radiosity too. The problem
was that light was scattered back to the dark surface of the moon.
The neat solution to that is to use also an interior_texture for the object
you use as sky sphere (which could be anything, including a vertical plane
like in the image below).
Make the side turned towards the universe (and the moon) totally dark (rgb
0) transmit doesn't matter; and the side towards the camera with the usual
texture as described by Bill. Now you can use radiosity in your scene,
without the lighting up of the shadowy part of the moon!!!

Interesting. Pure chance, but I've never actually tried using radiosity with
a moon. Good fix. I'll keep that in mind when the scenario arises!

Yes, this works well. One correction: it is better to set transmit to 1 for
the outside (black) texture.
Another interesting side effect is that you can put the light wherever you
want, in- or outside the sky object, without any lighting loss.

Nice light.
Perhaps a little groundfog would improve the scene
