Thanks Dunk!
As with so much of this stuff, it's a case of try it and see what results you prefer!
My access to dark skies is limited, so I'm trying to find a starting point that will yield results that are likely to work. But yes, loking at the graphs, the blue channel is always going to require about 20% more as it's only about 80% relative to the other channels. Thanks for pointing that out.
I was coming at this from the point of view of planetary, but exposing for the same skyglow levels makes a lot of sense for DSO.
Best,
Markus
