I think it is dust. More data will tell.

All opinions welcome.

not sure bert as some of the area is greenish in colour, though the bottom right may be dust?

I think all galaxies are way way bigger than shown clearly in most astro images. You see the occasional really deep shot like these LMC images and they inevitably show a huge halo of stars strewn around the outer reaches of the galaxy. Mike's Cent A shows that.

See this article for example:

Looks like I will need twelve deep panels to get the lot Ben. Great image.
