MAGIC is a system of two imaging Cherenkov telescopes exploring the Universe at energies above few tens of Gev. Achieving the lowest possible energy threshold is crucial in order to detect extragalactic sources characterized by a soft gamma-ray spectrum and/or far enough to suffer a significant extinction due to absorption of gamma rays against Extragalactic Background Light. We present the results obtained applying a novel image cleaning technique, optimized for sensitivity at low energies, to archival observations of extragalactic sources where the signal is expected to be concentrated around the energy threshold.
