Charge and Lorentz violation in black holes can cancel in lensing observables, yielding bounds on the violation parameter from M87* and Sgr A* shadows and on both parameters from QPO data in two microquasars.

Strong gravitational lensing and Quasiperiodic oscillations as a probe for an electrically charged Lorentz symmetry-violating black hole
Charge and Lorentz violation in black holes can cancel in lensing observables, yielding bounds on the violation parameter from M87* and Sgr A* shadows and on both parameters from QPO data in two microquasars.
