It is meaningless to compensate for white balance with astro images. Signal is signal and how you put it together for a final image is almost purely what you think the object looks like from the last image you think you saw.

The filter in front of the sensor of modern digital cameras tries to modulate the sensors spectral sensitivity to match the human eye sensitivity. The further complicating factor is the ambient illumination which can shift colour balance. Our eyes do this automatically!
This is what colour balance attempts to do.

Removing the filter to 'modd' the camera makes it far more sensitive in the far red to pick up HA which we can barely perceive. So if you then balance again you lose HA sensitivity so defeating the reason for removing the filter in the first place.

If you worry that your red histogram is way higher than green or blue just do what I do, ignore it!

Setting the colour temperature to 4000K when converting from RAW to TIFF will compensate without losing data in the red channel!
