I just adjust the colour balance until it looks like it should. Others may use tools or specific tests to get closer, so maybe someone else may comment.

Hi Theo, that's what I'm trying to avoid. Because when you think about it, every DSO is going to end up with a different color calibration if it's based on a "pleasing" colour. I'm trying to work out a consistent base to start from. I heard people shoot a G2V star and calibrate like this. Other shoot a grey and white card in daylight. I need to find a quantitative way to work out the basic R G & B ratios for my QHY8. Then when I shoot in the dark I can have "correct colors" to start with. I don't know. Should I shoot a know subject in broad daylight on 1ms then have a look at the colors and match the ratios this way?
