Making adlustments with RGB Combine Tool

Hi Community,

I am working on an image of Cave Nebula.   I have integrations for LHaRGB.   I have tried all the standard blend options in the RGB Combine tool and decided I prefer the result of HaRGB1/2 options as the best starting point for further processing.

My problem is that when I get to Calibrate Star Colours the red nebula colouring turns very blue or magenta which then seems impossible to correct.  

I think the reason for this problem is that the star colours in the RGB Combine output are all Orange/Yellow causing CSC to make a major shift to Blue to achieve a more correct balance. 

Assuming my reasoning is basically correct, can anyone suggest what adjustments to make in RGB Combine to increase the proportion of Blue in the Star colours?   I find the bg sliders in the Combine tools very effective for adjusting background colours,  and the above strength slider for adjusting mid-range colours, but there seems no way to markedly adjust the star colours without also greatly changing the low and mid-range colours.    Unless I am missing something CSC tool always adjusts colours across the full gamut not just the stars, so it seems to me there is a gap in coverage here.

Maybe CSC should have slider to adjust how much the star colour adjustments should be applied down through the luminosity range?
