AnotherAstroChannel | Pixinsight - Stretching using Pixelmath @anotherastrochannel2173 | Uploaded October 2022 | Updated October 2024, 1 hour ago.
Update-Version 5! - I have updated the stretching maths for both Linked and Unlinked in which I have added a function to modify the stretch curve shape, so a curve value of 1 is the same as a STF midtone stretch curve (normal stretch). If you increase the value to say 1.05, you will get more of an "arcsin" style curve which will help prevent blowing out the nightlights. I also added shadow clip protection. Last, I removed the GHS pixelmath script because it was difficult to use, and the actual GHS process within Pixinsight is so much better.
Here is the download link:

Note: The PixelMath script within this download link will be updated if changes are needed.
Enjoy!!!
