HUGE interaction trail!

Hard to tell if its related to the galaxy. Its in an incredibly nebulous region.

Right, if you turn up the Brightness slider you can see all the Galactic cirrus in the region.

Yes, I looked at that, but it seemed to me that there was a trail between the small galaxy lower left and the larger one in the centre, and another bridge to the galaxy at 2 o’clock. It looks distinctly different in density and brightness from the rest of the general fog in the region to me. And looking more closely, I think it might actually be two separate trails, one between the foreground galaxy and the small lower one, and another between the smaller galaxies at top right.

…and if you look in DR9 or SDSS it is even more distinct.
