Hi Stefan,

I always prefer not to use the colour balance controls on the camera itself, as it is often not clear whether these controls perform a digital adjustment of the channel levels or are a separate analogue gain on each channel. Most cameras are the former which is the case where it is potentially damaging to your image data to use the colour balance controls. It's better to colour balance at the final stages of image processing (after stacking, etc) - the Live Stack colour balance controls work that way.

However, from the point of view of taking flats it doesn't really matter much - flats are concerned with how much brighter or dimmer different areas of the image are under even illumination - that's governed by vignetting, dust specks, etc and the colour balance settings will have little effect.

cheers,

Robin
