Anyways, for Jubel though I guess some other people might wonder about this. In order to search for a black hole you can use the star browser tool just above the magnifying icon on the left of the hud.
I'd position yourself in the center of a galaxy, as the browser searches specifically in a designated area around you. You're going to want to click "filter settings" and set the system's main star as a black hole. I'd change the search radius to something like 1000 light years, though a warning, it's probably going to freeze the program for a second or more. Stuff should pop up, if not, increase the radius or try another galaxy.
