BatchPreprocessig

I was wondering if anyone could help me out on the settings I'm using for BPP.  My results leave my linear data with a pinkish hue that dominates bright stars during post processing.  I tried fixing the problem with the Repaired HSV Separation script detailed here: http://pixinsight.com.ar/en/info/processing-examples/28/maskedstretch-stars-sores.html
I set the DSLR_RAW preferences to "pure raw" before beginning BPP.  The files are .CR2 files.  The examples provided are that of linear data and the results of a simple masked stretch.  Thanks to all in advance and clear skies, Paul.

the pink star cores are processing artifacts due to data that's saturated in just some of the channels. one solution is to take some shorter exposures and blend them in with HDRComposition; that gets rid of the saturated data.

additionally, generally speaking most images have some kind of color cast until you do BackgroundNeutralization and ColorCalibration.
