It's possible to see the acceleration disk behind the black hole from both sides. Above arch is the upside, below is the downside. That's the outermost disk.

It's possible to see the acceleration disk behind the black hole from both sides. Above arch is the upside, below is the downside. That's the outermost disk. It's also possible to see the up- and downside of the front part of the acceleration disk from both sides second time from the light that circulates the black hole. I think the fuzzy part that joins photon sphere is the light from the upper part of the front of the acceleration disk. Going once around the black hole. When you go you go off axis (upwards) the lower side becomes fussizer/wider and other side mixes with the photon sphere.
