The Local Group galaxy M32 has a long history of serving as a test bed for interpreting the spectra of galaxies. Unfortunately, the vast majority of spectral studies are of the central regions of the galaxy, where stars can not be resolved using conventional imaging techniques from ground-based telescopes during natural seeing conditions. However, the situation is very different in the near-infrared when optical and atmospheric aberrations are corrected using AO systems. I will discuss imaging and spectroscopic observations of the central regions of M32 obtained with various combinations of AO systems and instruments on the Gemini North 8 metre telescope. These data allow the most luminous asymptotic giant branch stars to be resolved to within a few arcsec of the galaxy center, and provide a powerful demonstration of the capabilities of AO systems on the current generation of large telescopes.
