Removed hydrogen data from the stack. Stretched in Siril using the GHS tool with the Human weighted luminance method, which gave the galaxies a more interesting color, in my opinion. As for IFN, probably to bring them out better, about twice as much integration time is needed.

LRGB :
L - 6h 18min
R - 2h 50min
G - 2h 51min
B - 2h 36min

Подвытянул пыль, применив другой подход к наложению luminance данных.
