The previous ,10 panel version is here:

After adding 5 panels extra the "Volcano shape" with M81 at the volcano top is clearly visible. This is an annotated version.

The Integrated Flux Nebulae (or Galactic Cirrus) are 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. These IFN are very faint and where discovered in 2005 by Steve Mandel. This mosaic shows sections of 2 main Nebula in the Mandel-Wilson Catalogue, the Volcano Nebula (MW3 near Messier 81/82) and the Angel Nebula MW2.
