OK, that's good.

RGBWORKINGSPACE was only done because I am very new to pixin sight and a tutorial I read suggested to do it to images. To be honest I'm still not sure of what it does however I have done it before and got good results out of ColorCalibration.

The default working space is intended to match our perception of colour (e.g. green is heavily weighted.) The only time I have messed with a 1:1:1 space is for extracting a synthetic luminance where I wanted equal weighting. I'd be interested to see the tutorial if you still have a reference to it, but I'd recommend you skip this step.

I presume you're doing structure detection when you pick a star field as the white ref?
Another thought: you're not doing the STF with the colours unlinked are you? Weird stuff will happen if you do an unlinked screen stretch and then colour calibration.
What does the ColorCalibration process display on the process console when you run it? It should tell you the coefficients it used to adjust the R, G & B levels. That may hint at what the problem is.
Apart from that I don't have any clever ideas. I'd be happy to have a play with the image if you can put it on Dropbox or similar and PM me.
Cheers,
