Thanks all for you kind comments and suggestions.
I've tried a pulling back the red and boosting the green and blue a tad and the result can be seen below. However, in doing this and taking note of jay-qu comments about the star colours, I noticed that saving the file as a JPEG was knocking out the colours of the background stars. I've saved the image as a gif and you can see the difference in star colour. Anyone else seen this happen?
Alex, I intend to finish the job but am having a slight problem with cloud at the moment.
