A Pair of Pairs

With "galaxy season" underway in the Northern Hemisphere, I thought I’d shine a spotlight on two pairs of galaxy pairs. First up, the Whirlpool Galaxy, or Messier 51a, along with its companion dwarf galaxy Messier 51b:

Next, Bode’s Galaxy (Messier 81) and the Cigar Galaxy (Messier 82):

As with many galaxy images, there are lots of other smaller or more distant galaxies within view. How many of these galactic photobombers can you find?
