How often do you see mergers and is this important?

    I've not seen one and have looked at a couple 100 galaxies now. Is this something special?

    Am not sure this is a merger. I see two ETGs (early-type galaxies), almost certainly ellipticals. I also see considerable color artifacts. ETGs that appear to overlap are common, especially near the centers of rich clusters of galaxies; sometimes they are interacting, but as far as I know mostly they are just chance alignments.
