We have attempted to resolve the system containing the Cepheid V1334 Cyg ADS 14859 using both the Faint Object Camera FOC and the Fine Guidance Sensor FGS on the Hubble Space Telescope, and also using ground-based speckle interferometry with 4 m class instruments. None of these approaches was successful, leading to upper limits of approximately 20 mas depending on the magnitude difference between the stars. We discuss constraints this places on a possible wide orbit as a guide to future observations.
