We discuss penumbral fine structure in a small part of a pore, observed with the CRISP imaging spectropolarimeter at the Swedish 1-m Solar Telescope (SST), close to its diffraction limit of 0.16 super([image] ). Milne-Eddington inversions applied to these Stokes data reveal large variations of field...
