Abstract: We present new imaging and spectroscopy of the post-red supergiant binary AFGL 4106. Coronographic imaging in H alpha reveals the shape and extent of the ionized region in the circumstellar envelope (CSE). Echelle spectroscopy with the slit covering almost the entire extent of the CSE is used to derive the physical conditions in the ionized region and the optical depth of the dust contained within the CSE.
