Hi
Following some suggestions I have reprocessed this imagewith particular respect to sharpening and the background noise, I have reduced both although there is still a bit of noise evident it is not as bad and to get rid of it completely would have meant an artfificially smooth image, more subframes will be needed to improve it further, thanks for looking
Best wishes
Gordon
