Thanks mate. Was thinking more about this after posting. Might post a link to bigger image, and looks a little magenta instead of red like you'd expect. Will play more tomorrow.
brutal hahaha, theres not too much to be brutal about, you seem to have the guiding down pat and the FF is doing its job flattening the field.
If you can guide for 4 minutes, hit 10, the difference is amazing! and the ed 80 needs that extra time open.
Processing, keep your eyes on the histogram working with levels to expand the individual channels R,G,B. and also keeping them aligned. Opening up your image the red part of the histogram was double and can be seen in the darker areas and red stars. the rework still shows those lovely blue/yellow stars but allows the other colours to come on though. if you have a look at my eta carina there is purples, pinks, reds, blues.
I call it aligning and expanding the channels it gives you powerful control over colour and saturation.
this is interesting, im either colour blind to green or somethings going funky because i cannot see green on this computer or my eepc, i have one other friend that says he sees "funky green colours" in my images. I utilize the Spyder3 pro for colour calibration of my monitors and when i print to a colour calibrated epson photo printer at the uni they look exactly like they do on the screen. Could you look at my other images and tell me if you see funky green colours.
I'm aware of the red. You should have seen the unprocessed version just after stacking. I wasn't sure how to handle it, because I know there's a lot of nebulosity in this area. I set the black points at the darkest areas - top right corner and also that dark patch at 9 o'clock middle.
Thing that's really bugging me is the kind of magenta tinge. Is that the real colour? I thought it should be more red. Couldn't for the life of me get the colour balance right the way I envisaged it.
@Brendan - if you're using Photoshop, use the info window instead of eyes. Press F8 to bring it up. Hover mouse over the area you think might be black/neutral, and you can see the R, G, and B values at that point. You can set it to use a 3x3 average instead of a point, smooths out noise etc. Very handy to see colour biases using numbers.
I reworked the original and provided a link to a bigger version. Please check out the bigger one. It turned out better than I imagined possible. I'm tickled-pink right now with the results.
Thanks mate. I am stoked. It's amazing the results you can get when the clouds stay away, guiding works, dew controller keeps the dew-monsters at bay, focus doesn't shift, software generally plays along, and things go well. But how often does all that happen?
Hope you don't mind i did a repro as an experiment, i used photoshop to blend a sharpened image with more blue useing layermasks. I drew on the mask with a 20% brush to highlight the points of contrast.

I don't mind, but are you sure that's my image you edited? Think you may have mixed my thread up with someone else's?

I think Brendan's on the money re:color process.
