Histogram is based off the jpeg preview baked in the RAW. This is why I am asking re: choosing a flatter film sim when shooting in the field.

I haven't done any dark sky shooting (hard to do in NYC) to test whether the DR100/DR200/DR400 affects the RAW. Many mixed opinions whether it does or doesn't from the threads I've gone through.

I will try Sequator in Linux after the trip.

To my knowledge, the histogram in RawTherapee has nothing to do with the embedded jpeg. It either from the RGB data cooked in RT, or you can also toggle he actual raw histogram if you want.

And from a recent shooting I've done with DR400 setting, the raw file produced is just a plain underexposed ISO 800 raw file. In other words, for astrophotography stay away from DR settings. And forget about the camera histogram, the night sky is mostly black, it's logical that the histogram is to left.
