This is the Leo Trio of galaxies, with NGC 3628 ('hamburger galaxy'), to the left, M65 top right, and M66 on bottom left. These galaxies are about 30 million light years away from Earth. I made an effort during processing to show background galaxies and the faint inter-galactic clouds, the most prominent of which is the 'tail' going down and to the left of NGC 3628.
