Thanks Thomas.
The only problem with this method is that the Moon is coloured by the 
Sphere of the Sky (we need a name for this as skysphere is something 
else). In your example the sky is too light, in my opinion. But it 

example, looked washed out.
For a darker blue sky I got slightly better results by using a small 
fade distance and a large colour value but I suspect that I would need
