This is the first of 3 images I took last night. After 1 1/2 hours the object was too high for the POD dome, so had to stop. I will try to get some more subs as some point as the background noise still needs some work.
I have always struggled to get star colour, but have managed to pull some out on this.

Very nice Carole.
I like that Carole, nice resolution but the colours look a bit off to me - could it be the CLS filter has shifted the colour balance?
Robert
Nice capture.
Mac.
Quotenice resolution but the colours look a bit off to me - could it be the CLS filter has shifted the colour balance?
Don't know Robert, as I said above, normally I don't get any colour with stars, all I did was increase the saturation a bit. Seeing as I never normally get colour I've got no experience in this.
Any tips on how to get star colour would be appreciated.
I tried Noel Actions (increase star colour) but that didn't look nice at all, most of the outer core became blue with a burnt centre, so I abandoned that.

The image does need a bit of colour rebalancing I think. You've captured the stars nicely without burning out the core - so you have all the data available. The stars look nice and round.
It's interesting to compare this to Duncan's version - again using a Canon with CLS filter:
