Update: this is with media jitter 0.1. I found that with too much jitter
the sky would go noisy and spoil up the lovely clarity effect (and also
hide the superb 6000x3000 starfield texture). I did experiment with
UberPov's anti-aliasing mode 3 but couldn't make it behave --- I'd
either get sparkles on the water or jaggies on the mountains, and either
way it would take an age. I'll also experiment with radiosity and see if
that makes a difference.

Also I should have rendered this as EXR and tone mapped it, curses curses.

The Earth needs to be *brighter*. Except that it's illuminated by the
sun, so I don't have direct control over it. The cloud layer is diffuse
1, so it should be reflecting brightly, but it seems not to be.

(I should point out that this model isn't just this landscape: I'm
rendering the *entire moon* here. I can change the camera position and
time of day arbitrarily, including shots from out in space.)

Are you talking about Erath's clouds or the closer Moon's clouds.
If the later, did you try using backside illumination?
Just change the cloud's finish to diffuse 0.5 0.5 as a start point.

That's a very cool feature now POV-Ray supported. Here is its description:
