In many astronomical images, there are dark structures, or dust lanes within the galaxy or nebula. Through stacking and stretching, these dark dust lanes start to get brighter. We want to bring back the darkness to these areas.
Dark Structure Enhance – Basic
PixInsight includes a script called Dark Structure Enhance (Scripts – Utilities – Dark Structure Enhance).
The script will automatically improve the dark structure within the image.
What’s Next
The next step is optional, and that is to reduce the star brightness with PixInsight Morphological Transformation.
