I did this image a while ago and thought I should reprocess it some more as it wasn't quite there.
I think this is the best I can get out of my CDK17 at my home observatory which has around 7/10 skies. My dark site is more like 9.5 out of 10 and sometimes better. So I think I'll have to drag it down there for a week or more soon to see what it is really capable of as I see Martin's images being quite a bit better using much the same gear. Apart from his excellent processing the rest should be the skies.
Still, I am quite happy with this image. 18 hours and lot more was taken that was rejected.
