7th July 2022 First test of the GHS (Generalised Hyperbolic Stretch) script in PixInsight which I found intuitive (for a PI script!) and mighty impressive in its results. Definitely one to keep using and get good at. This resulting image is a massive improvement on the same target photographed last year due to this and, mainly, the EQ6R Pro mounted on a pier.
