Thanks everyone.
I've done a revision, its on Astrobin

Patrick - Yes mate - Sunday night from 7:10pm through to about 2:45am by the time I finished taking flats...
It was such a shame to be backing up while its still clear outside, however, work on Monday at 8am was already difficult enough with a 3am bed time!
I'm hoping this weather backs off, I really want to add another 6h Lum, and another 1~2h each of RGB...
I'm quite happy with the result thus far - but its a long way from 'complete' in my eyes.
