Think it's M110, but I don't have astronomical skills...
I could find no good maps comparing the ED skybox with real galaxies, so it's really wild guesses from me.
I think so.
As seen from SOL
Blue blob is definitely outside our galaxy.
Looking at Google Sky, I guess my vote is IC 1502. I could be wrong, though. This seems like the most prominent object in that direction not in the Milky Way.

Take a look at the stars around there. Are any of them visible from Sol in Elite? Perhaps you can use this to triangulate the object you're observing in game and see if it lines up with IC 1502.

My problem is that I immediately get lost when looking at this data; I have no idea how to compare it with the ED skybox.
Try this one: https://in-the-sky.org/data/object.php?id=IC1502
The finder chart might be a bit easier to read for picking out stars that are in Elite and see how they line up than the wikisky one?
