I continue testing the new VeraLux scripts by Ricardo for Siril. I recommend everyone try the VeraLux Curves script—it's an amazing tool.

The VeraLux SyQon script is very interesting; I think with time and some refinement, it will replace Starnet.

I also recommend:

HDR-Multiscale — a compression tool: it smooths the brightest peaks (dynamic range) to reveal details hidden in the highlights, such as a galaxy's core.

VeraLux Revela — a local contrast engine: it adds "brightness" and depth to mid-tones and faint structures (texture), rather than compressing the light.

In PixInsight, there's HDR Multiscale, but it doesn't seem to stretch. But it works well. I used it on globular clusters.

Unfortunately, I don't have Pixinsight, but this script works well in Siril.

The background is crimson, there's a green haze around the galaxy, there's no contrast in the galaxy, the core is choked—roughly this needs to be fixed.
