Weather forecast lied - i was supposed to have clear skies from 11pm until dawn - in the end only patches (5 mins worth) of clear skies appeared up until 2am - during these patches i focused, drift aligned and found my target.
I then set it going capturing 122 images - of which i ended up rejecting 52 because of cloud cover / wind movement

Final image had 70x2 minute subs

I suffered on Xmas morning though as the cold i was almost shaking off - came back with avengence and put a small damper on the day

but ... the final image i am pleased with - so all good :)
