Description

M81 group behind a rather dense veil of the IFN, shot from moderately dark skies (B5).

When I started collecting and processing this picture I was mostly after the galaxies themselves, only when I discovered all that mess that popped out of the background did I realize that it would be more about the IFN than the galaxies.

Canonically, the Ha channel was used to enhance the Ha regions in the galaxies.
