Thankyou everyone for your compliments on my latest image. You are all too kind (except bitter and twisted, long focal length Fred

)
Jase: you are quite right I wasn't totally happy with the combines either but I have learned to be happy with mediocrity
Marcus: I also like stars in the image and I agree I would have liked a little more saturation too but my HaRGB combine technique wouldn't allow any improvement in the saturation without screwing up the image

.
Thanks again everyone
