Thanks everyone for your comments, was away all weekend so have not been able to respond.
Roberto, my stars in the subs look very much the same as the ones in the final image. No real blow out visible in them at all.
Steve, thanks mate. All good on the colours we are all different there
I like to leave my colours as taken because if I could see the object from my backyard that is what I would see.
David, thank you. I gave it a go but I think I may have wrecked it
New image attached.
