Planetary Nebulae are proving to be powerful tertiary distance indicators as well as sensitive probes of a galaxy’s velocity field and mass distribution. We present a new technique for determining the positions, luminosities and radial velocities of the PNe in an external galaxy which may enable a one-step measurement of all these parameters.
