M81 and M82
This galaxy field in Ursa Major contains two very bright Messier
galaxies: the beautiful spiral M81 and its active-core neighbour M82. The
other bright galaxy in the field is NGC 3077. To the left of M81 is one of
its satellites, the faint dwarf galaxy Holmberg IX. Several other faint
galaxies are also seen if you look closely in this rich field.
Also faintly visible in this field is the integrated flux nebula, which is
what is causing the subtle unevenness of the background. See the
Mandel-Wilson Unexplored Nebula Project at www.galaxyimages.com/UNP_IFNebula.html
for more info about this.
