The circumstellar environment around Eta Carinae is polluted by a complicated field of ejecta which is the product of several historic eruptions. At least two regions are uniquely characterized by narrow high excitation emission features: the Wiegelt Knots and Strontium "Filament." We have produced the first sub-arcsecond spatial maps of high excitation emission from individual spectral features within a few arcseconds of the central star. These maps provide helpful insights into the general shape of these regions, their probable origins, and the excitation mechanism which powers them.
