Done over 3 nights 400 ISO
Sunday 22nd July 2 x 600 secs (then disappeared behind the dome)
Monday 23rd July 13 x 600 secs
Tuesday 24th July 10 x 600 secs
Total 25 x 600 secs (4 hours 10mins)
Modified Canon 450D, CLS filter
Guided with QHY5 and PHD on NEQ6
Captured in APT with dithering, processed with DSS and PS CS3
Not posting a larger image as it's not worth looking at, too noisy and typical for a DSLR at 22 degrees at night!!!!!

Carole,
That's a really interesting area of sky. I understand why it looks a bit noisy given it's a DSLR on a warm night from a light polluted location but I fear that something has gone horribly wrong with the colour during processing.
You'll see what I mean if you look at my version from last year:

I remember the first time you processed the Pelican you had a similar problem:
http://forum.orpington-astronomy.org.uk/index.php?topic=8407.0
I wonder if this is a similar issue?

I agree Mark, it was very washed out in colour and I actually was looking at your image and others on the internet while I was processing it and so increased to red and saturation manually trying to get the colour right, looks like I got it wrong.
I'll have another go
Carole
OK, I have had another "go" is this better? at least i have managed to get a bit of star colour this time (and horizontal banding!!)

Hi Carole,
It's slightly better - there are some star colours.
But sorry to say, something still looks fundamentally wrong :-(
Something is not quite right in your processing sequence.
Thinking about it I think the main thing I don't like is the uniform salmon pink - which seems to be a common Photoshop symptom - Google for "photoshop salmon pink astrophotography" and you'll find lots of stuff which may or may not help.
