When I stretch my data I take care not to saturate the brightest areas, including the stars. This allows for colour to be maintained during processing.

Yes I should have made that point too. I get core saturation but not total saturation, and that means I have colour around the outer edges of the stars. Only really bright stars are over saturated.
