Those stars are in our own galaxy.
Could very severe stretching just simply be showing up the diffraction
halo?
And combined it is sort of like a coarse blur mask being applied to the
whole image?
If not, it is a way cool VEEEERY deep image

Obviously the
stars are bloated from the high contrast stretching and thus encroach on any Cirrus that may have been near to them but the rest is very real and it is pretty clear to me
you can see it all in the LRGB, the high contrast stretch just makes it more obvious.
In case you didn't notice it in my album there, the UK Schmidt doesn't lie in this slightly
less aggressive stretch comparison
