The solution was to cheat! Basically, the problem getting the
composition of crescent and Earthshine right was to deal with the
terminator properly. This is virtually impossible because the two
images don't actually fit together due to over-exposure. The way
around this is to take an Earthshine image on one night and the
crescent image on the subsequent night. When these images are merged
together (e.g. using Photoshop's lighten layer blend) the overlap
removes the terminator issues resulting in a much more aesthetically
pelasing result. Well I got excited about it anyway ;-)

Pete,
There was a very impressive effort on LPOD (Lunar Photo of the Day)
about two years ago which made a great impression on me. Take a peek at
the following:

There's a new one on there today ;-)
Looking at the position of the star just off the limb in the
Earthshine image and in the composite, I think I sent the wrong
Earthshine version over. I must admit that in a moment of tiredness I
didn't label the layers in the composite like I would normally. The
trouble with digital is that you can end up with a whole host of
images that all look very similar! Ho hum!
