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
