I am having no problem now thanks to some insightful help on this forum and reading Keller, with BPP, but even with following Keller I am having problems with my integration results when I proceed with the full PI pre proc. I think too much red. I am just not sure.
But here is what the integration of my Orion Nebula looks like using the full PI pre-proc algorithm re Keller. The only thing I did differently was not check off optimize dark ( i did check off calibrate) when calibrating the flat frames.
The attached is what I am getting.
and this is my astrobin of my BPP w PI post -proc (same data set).

Here is a link to the integration file:
