I had a little play with your image. I hope you don't mind. All I did was stretch a little more of the red channel in curves, dropped the brightness a touch and moved the histogram a little more to the left and balanced the colours using levels. The white or blue white stars are very bright and make adjusting them on this image imposible. You may want to look closely at the way you apply curves and keep the brightness down a bit.
Hope this helps.

Doug, thanks so much for the advice, of course I didn't mind you having a play with the image. You made such an improvement it's hard to believe it's the same image
Your advice is very useful, I've had a quick go at the original image and the improvement is amazing.
You've led me down a new track. More to follow.

Hi Narayan, I just tried Kappa Sigma with the same subs and I think the result is better. Processing using Doug's advice should produce a better image. I did find that average worked better for my Horsehead though. I need to learn more about how these stacking methods actually work
Thanks all for your great advice!
