VERITAS, an array of four imaging atmospheric Cherenkov telescopes, is designed to observe photons at energies from 85 GeV to greater than 30 TeV. VERITAS has been used to study active galactic nuclei, remnants of supernova explosions, TeV binary systems, and search for dark matter signatures, just to name a few. However, the typical methods for analysis of VERITAS data are ill suited to studying highly extended sources of TeV emission (greater than ~1 degree across). A nearby supernova remnant (Geminga) and a cocoon of TeV emission (the Cygnus Cocoon) are examples of such sources that VERITAS currently has observations of, but has thus far been unable to detect. I will present a new technique for analyzing VERITAS data and studies demonstrating it's potential use in revealing sources with high angular extensions.
