Big learning curve with CCD Stack. I followed Adams Blocks videos which I highly reccomend. I love this program now that I am familiar with it after spending several hours playing.
I effectively just treated this like LRGB and broke each of the colors from the OSC file into their own RGB files then created synthetic luminance.
I find it easier to process this way than trying to process a single color image.

2x2 binning will make stars rounder but of course costs resolution and gives fatter stars.
Squarish stars with mirrored scopes comes from the secondary vanes being thick. I have seen that with Tak BRC250 to some degree.
As you say different interpolation methods may get different results.
CCDStack 2 has quite a few interpolation methods now.
Collimation will affect star shapes as well so perhaps some of that in there too? You see it in your 1x1 downloads better than we would in a final image.
Greg.
