Assigned ID: 450 ----- Submission 1 (Fri Jan 21 22:18:58 GMT 2005) ----- The number of distant galaxies seen in ACS imaging of M101 can be used to probe the extinction in this spiral galaxy. The ``Synthetic Field Method'' (Gonzalez et al. (1998), Holwerda et al. (2005a)) can be used to calibrate this number for crowding and confusion effects. The ACS fields in the archive are a uniquely suitable dataset for such a project. The total extinction of the disk in relation to the infrared emission, HI column density and disk light should reveal more on how the dust component relates to all the other constituents of the spiral disk of M101.
