I am resigned to the fact that deep sky DSLR work from the burbs is difficult enough but on a night when it was 33 for most of the night - horrible. With the light pollution filter the colours of objects are pretty hard to get. i have to work out how to get some better colour balance in the images i have taken, but for now here is the image - wear your sunnys also a shot of the noise.....
Thats an impressive image. Loads of detail. Trade off for imaging in light polluted skies is colour variance - but PS Selective Colour helps a lot. Otherwise its pack up the entire kit and travel far far away!

Go back and make sure you don't clip your shadows and check my tutorial out on balancing color bias....It will help.
mmmm Louie (careful not to call you Louise ) i have attached the histogram for the image not sure where i clipped the image But then i dont use photoshop much - however the same principles apply

Yep,not clipped according to that histogram mate...but It does look like color bias needs balancing....this is why I won't let go of PS.
Colour bias is handled usually with levels/curves and an eye on the expanded histogram. Perhaps also easier with colour balance tool in PS.
Or you can do a custom white balance using an 18% Photographic grey card shot at midday as the reference for the custom white balance saved in the camera itself. Every shot after it is setup is adjusted using that custom white balance.
Then your colour downloads will be closer to usual colours with still a hint of too much red. But then it is far easier to correct.

i have tried to do that a few months ago - with a lot of rain in between so will have to redo again. LOL its only art
my biggest problem is the CLS filter giving a huge colour shift
I wouldn't be complaining if I could achieve that from the 'burbs...
I've been processing my modded 350D shots (well, the last data was 6 months ago) using Maxim. I set the colour conversion / debayering to R100% G110% B120% (or even140%). It certainly helped to boost the blues in my image of M20.
I read a tutorial by Michael Covington that suggested this as a way of preserving colour balance.

i might have to read that and see how that will apply to my processing in PixInsight?
yes heat stroke
