While waiting for the big nebulae next summer, I tried my hand at capturing the two famous galaxies M81 and M82, highlighting the surrounding IFN.
This is a very dense region for galaxies, there are not less than 126 galaxies in this image !
What's the IFN ? The iFN is high galactic latitude nebulae that are illuminated not by a single star (as most nebula in the plane of the Galaxy are) but by the energy from the integrated flux of all the stars in the Milky Way.
