Directly observing exoplanets with coronagraphs is impeded by the presence of speckles from aberrations in the optical path, which can be mitigated in hardware with wave front control, as well as in post-processing. This work explores using an instru

Coronagraphs are powerful tools to probe the direct neighborhood of stars at very high contrasts but their vulnerability to wavefront errors however makes them less efficient for observations at angular separations smaller than two or three resolutio
