We propose a pilot study of the O-rich planetary nebula (PN) NGC6543 (Cat's Eye Nebula) in order to investigate elemental abundances, mass loss, dust grain composition, and nebula shaping process based on GMOS slit-scan emission maps. Using a large number of emission lines detected from the GMOS spectra along with the mid-IR Spitzer/IRS and our own far-IR Herschel/PACS spectral maps, we perform a comprehensive spatially-resolved analysis of the circumstellar matter in NGC6543. For the first time, we will determine spatial distributions of 11 elements (He/C/N/O/Ne/Mg/Si/P/Cl/Ar/Fe) or more for NGC6543 self-consistently without any simplifications such as the ionization correction factors. Using the 3-D datacube generated by GMOS, we investigate how asymptotic giant branch (AGB) nucleosynthesis elements are mixing with surrounding ISM and time-variation of mass-loss rate. By comparing the spatial distributions of [Mg,Si,O,Fe/Ar] with the silicate dust emission maps, we directly determine the silicate grain composition. Our 3-D elemental abundance maps, mass distribution maps, and kinetic energy maps would give strong constrains to modelings of AGB star evolution and PN shaping process. Thus, this study will be an important step to renew our understanding of O-rich low mass star evolution and material recycling between stars and the ISM.
