Description

This image was my greatest challenge. This is really not obvious how to process an image with this huge dynamic difference. The galaxies are bright, the IFN is extremely faint. I managed to solve it with only one intensity mask on the galaxies. The prize is the noise, but photography is the art of compromises.
