If it is quiescent you can image it indirectly of the material and stars orbiting in close proximity to it. And/or anything passing behind it. A feeding black hole with an accretion disk doesn't eat *all* the light or matter - they are believed to be responsible for powering the relativistic jets in some of the very brightest objects in the universe. M87 is a local example. Regards, -- Martin Brown
