StarSatGuard [SSG] has been modified quite a lot. I removed access to the SSG Threshold value. This threshold is now permanently set at 65,534. I discovered that SSG can be used in tandem with a custom Multiplier to achieve the equivalent of a large histogram stretch which will protect the stars from saturating. The net result is that faint nebulosity in your astrophotos are much brighter and the color of bright stars is retained. The bloating of bright stars is avoided but their halos are brighter. I posted a write-up…

CaLIGHTs dynamic range compression
CaLIGHTs Version 3.1.9 One thing I have noticed when I am preparing my astrophotos is that whenever I stretch a stacked image to reveal the faint details this also causes the bright stars to bloat and become pure white. I could never get away from this issue. This is because the dynamic range in most DSO astrophotos is huge! Most of this dynamic range is gobbled up by the very bright stars with only a tiny bit of the dynamic range allocated to the faint nebulosity and/or galaxies. Over the…
