Images of the dense center of globular cluster M 15 (NGC 7078) have been obtained with the HST in the V and I filters. Accurate photometry is possible in the very densest part of the cluster center with rms errors of less than 0.3 magnitudes for stars down to the main-sequence turnoff. Evidence for radial segregation between horizontal branch, red-giant branch, and blue straggler stars is presented. We discuss the possibility of the existence of a central stellar density cusp which does not flatten into a small central core at radii less than 2 arcsec.
