I have never seen the background halo and surrounding misty gases with a faint streak. Is there something blocking in front of it?

The faint streak is a diffraction spike (optical artifact) from a star outside of the image. See next post (image rotated and zoomed out)

#AGN the line from upper right is an artifact from an out-of-frame star
