The dome would have a lens on its side, to emulate gravitational lensing, with a black filter to simulate the event horizon. People could watch the simulated black hole in the night sky.

Cool as gigantic lenses in domes is as an exercise in lense-grinding, wouldn't it be much more practical (and, I imagine, fully baked in better planetariums since at least in mid 1990s) to just project the stars on a planetarium dome with one of the current generation fully computerized systems, simulating a BH however you wish (and can program)?
