In this paper we report a super-resolved reconstruction of a thin crystal of H-Nb2O5 in which the limit of continuous transfer has been extended from about 0.2 nm in the conventional axial image to 0.13 nm. To allow the reconstruction of crystalline fragments containing little stable amorphous material, modifications to the standard procedure for image registration have been developed. Both the modulus and phase of the reconstruction appear to contain directly interpretable information.
