Digitized versions of the Skylab S-054 solar X-ray images are now available from the National Space Science Data Center. The images can now be analyzed in unprecedented detail, using image enhancement and display techniques which have been developed since the images were made. New results of a project to analyze these images with software on IBM PC- compatible machines and other platforms will be described and the image products displayed. The technique of unsharp masking yields especially good results in improving definition of image features. Two to three times as many coronal bright points can be detected via image processing with unsharp masking, for example. Some images serve as quasi- stereoscopic pairs, and have been viewed with a variety of methods (stereoscope, blue-red composite and 3-D glasses). 3-D study of these large-scale coronal structures reveals unsuspected structures along the line of sight. Large-scale arches and polar plume and crown structures are observed, persisting for 12 hours or more. Filament channels are visible as canyon-like gaps between bright curtains. The margins of bright coronal regions, where they end at filament channels or coronal holes, exhibit an unsuspected overturning curl away from the coronal holes; this should be of interest for theoretical models of coronal holes.
