The stellar sky—as seen from the vicinity of a black hole—is discussed as a method to visualize the effects of light deflection. For rotating black holes, spatial axes defining the spherical angles of arriving light rays were defined via the direction of the plumb lines. Some light rays circling a strongly rotating black hole (extreme Kerr black hole) are also shown.
