I've now added the rest of the data into this and completely reprocessed
(the original quick attempt at processing was here: http://forum.orpington-astronomy.org.uk/index.php?topic=9264.0)
H-alpha modified Canon 350D (now with mirror removed!) on Tak Epsilon 180ED with IDAS LP2 filter. 46 x 5min subs at ISO 800.
Taken over 3 nights during the week 2-7 September.

I was very happy to get star colours in the cluster NGC 6802 - just to the right.
The small version above does not do it justice, so please take a look at the larger version:

Very nice Mark and it looks like the mirror removal has removed the squiffy diffraction spikes that you were getting.
Lovely capture Mark, great colours
Fantastic Mark. Best image of the Coathanger I have ever seen.
Very nice Mark, great colours
Now I know where to put my coat when visiting! I love the way you get the star scaling right. Lovely.
Nice one Mark,
It's a difficult field to process and colour balance but you've done a grand job ! Hopefully Mike will use this image rather than my embarrassing attempt in future :)
Really nice Mark - top notch result - John
Great image Mark........do you do it mono as well. ;)
