Looks like a dust cloud
I can't tell what this could be

It is an irregular galaxy. The red stars look brown in this image.
Dust is invisible, unless
It makes a silhouette against the galaxy such as a dustlane.
Or hot light,such as UV light shines on it and makes it glow purple
red or green, as in AGN illumated clouds, voorwerps or vorwerpjes
