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
is fine for a gibbous Moon. But when the Moon is a crescent you can see
part away to get the best result.
It is a work-around but all art is artifice.
Thanks to all.
