Abstract: Recent laboratory experiments have demonstrated extremely high contrast imaging near a bright point source (Trauger & Traub 2007), a prerequisite for coronagraphic surveys for extrasolar planets with TPF and precursor telescopes. As the technology is now maturing, the question of which stars to target and how to optimize a direct imaging planet search needs to be addressed, so I discuss scaling relations and analytic estimates for how to optimize the number of planets detected (not necessarily in the habitable zone), taking into account noise from zodiacal light, exo-zodiacal light, and speckle noise, as well as the diversity among stellar and planetary systems.
