I can provide some light polluted uncalibrated raw data if you wish to demonstrate. Got stacks of that.  |
The removal of the skyglow frees up dynamic range, which can be used to bin an image more until the whole of the dynamic range is used up. This would be fractional binning obviously and not a neat 2x2 - think 2,25x2,25 or thereabouts. The image would be smaller than the 2x2 hardware binned image with the light pollution still in.
You could do the same thing to the hardware binned image though - take out the light pollution and then software bin it again until the full dynamic range is used.
I'd be happy to demonstrate it!
