I was never happy with my original process of this, goodness knows what I did as it is pretty awful, so decided to take another look at it today.
It's still far from good, but a darn sight better than my original process.

Much better Carole! All that green has gone at last 8)
Thanks Roberto, but it wasn't just the green, I had lost much of the detail (goodness knows what I did it's too long ago) and the stars left much to be desired too.
Carole
Yeah, much more detail, and the stars aren't saturated, either.
Yes ~ much better Carole. More detail and so much more dramatic!
