We present detailed NLTE spectral synthesis models of the Type II supernova2005cs, which occurred in M51 and for which the explosion time is welldetermined. We show that previous estimates for the reddening weresignificantly too high and briefly discuss how this will effect the inferredprogenitor mass. We also show that standard CNO-burning enhanced abundancesrequire far too large an oxygen depletion, although there is evidence for asingle optical N II line and the sodium abundance shows clear evidence forenhancement over solar both as expected from CNO processing. Finally wecalculate a distance using the SEAM method. Given the broad range of distancesto M51 in the literature, the determination of a distance using Cepheidvariables would be quite valuable.Comment: 31 pages, 12 figures, ApJ (2007), in pres
