Black Hole Scene

I’m working on a black hole scene with stars that are supposed to be behind it, so it creates that gravitational lensing effect. However, I’m not sure on how to create the stars in a way that makes them “shine” (like in the image below). How would I go about doing this?

Glare node in compositor. That’s how it’s made usually. Otherwise set up volumetrics and wait for eternity - if there is some virtual lenses defect, that is ;).
