Description

I know that there is a faint nebula around this core and i can see it barely in the stack when performing a very boosted histogram-stretch, but i am not able to extract that nebula without taking a lot of noise with it.

Version B is just to show what i mean by "noise" :-) This version was stacked with Siril, which in fact brought a lot more of the faint nebula in the stack, but i reached a border here. The difference between the nebula and the noise is very tiny, too tiny for my processing skills, which are at a very beginning level.
