This image shows you a deep sky object bathed in northeast of Aquarius, near a border to Pisces. An elongated galaxy with 1.8 arc minutes in length has a number of MCG1-60-21, and an elliptic 4 arc minutes northeast is MCG1-60-22. A reversed image below somehow shows us a dimmed filament connecting those two minor galaxies. It's considered that the filament is inter-galactic stars or gaseous matters stretched by gravitational interaction between the closing pair.
