I continue to try new VeraLux scripts in Siril, and another one has been added—VeraLux Revela.

Revela is a local contrast mechanism: it adds "brightness" and depth to mid-tones and faint structures (texture).
Other scripts used for this image: VeraLux Alchemy, VeraLux HyperMetric Stretch, VeraLux Star Composer, VeraLux Vectra, VeraLux Revela, HDR Multiscale.
