Hi Dave,  Talk about jumping in at the deep end, massive gradients and enormous dynamic range to deal with. All the usual suspects are in there and easily recognisable, congratulations. When I eventually get around to taking and using data from different exposure times and accept the challenge to combine them, then I'll tackle this. Right now I know I'd struggle to balance it as well as you have achieved here with one set of exposures, so I'll wait and stick with lesser challenges. Great job Dave.  Best regards,  Ray 

Thanks Ray. I have another order pending with the same co-ordinates - 60x60s + 60x30s + 60x20s + 60x10s.  This should give plenty of data to experiment with for some HDR.  I used the 'remove light pollution' tool in APP to handle the gradient. I have just been comparing my effort against a Roger Clarke image of the same region using the same lens.  Mine is on the right - still a ways to go. Roger Clark Orion Region Dave
