      Do you take/use flats?

      A flip mirror probably produces bad flats because it exposes one side longer than the other, which would produce a gradient. I suppose it might be a small gradient if the flip was fast and the flat exps were long (dim target). And if it is highly stable and repeatable then you could calculate the gradient and remove it mathematically.
