Well, in deep sky imaging we always deal with faint signal, we have rather dark pixels all over the place, therefore different "dark" (levels or averaged frame) subtraction methods really makes a different overall look, it's a critical step for a good final result. I'll give it a try with white balancing after dark frame subtraction.
