so I'm creating a black hole in Blender 2.8 and am trying to distort the stars (around the blue circle in the screenshot) in the background behind the black hole. Unfortunately, I am having trouble applying this effect in the node editor. Does anyone know how to make this distortion effect like the one on this picture (blackhole pic)???
I have attached a link to the file here along with a couple of screenshots of my project down below.
