Hα images of the head of the Guitar Nebula. Bottom: Wide‐field image of the Guitar Nebula obtained at the 5 m Hale Telescope at Palomar (Chatterjee & Cordes 2002). High‐resolution images of the region marked with a box (~16^{﹩\arcsec﹩} in size) were obtained with the HST PC in 1994 (right) and 2001 (left). North is upward, and east is to the left. Stars are circled, and arrows mark constricted regions in the limb‐brightened Hα emission that are conspicuously brighter (see text). Note that the NS is located at the very tip of the nebula at each epoch.
