I will summarize the techniques and results of a recent telescope search for optical emission decaying relic axions using the VIMOS IFU at the VLT. Relevant theory will be reviewed and new limits on the axion's coupling to two photons will be discussed. If time permits, I will review cosmological limits to axion masses, and briefly how they may be evaded in extended reheating scenarios.
