We report time-resolved optical flux and circular polarization spectroscopy of the magnetic DA white dwarf HE1045-0908 obtained with FORS1 at the ESO VLT. Considering published results, we estimate a likely rotational period of P_rot≃2.7h, but cannot exclude values as high as about 9h. Our detailed Zeeman tomographic analysis reveals a field structure which is dominated by a quadrupole and contains additional dipole and octupole contributions, and which does not depend strongly on the assumed value of the period. A good fit to the Zeeman flux and polarization spectra is obtained if all field components are centred and inclinations of their magnetic axes with respect to each other are allowed for. The fit can be slightly improved if an offset from the centre of the star is included. The prevailing surface field strength is 16MG, but values between 10 and ∼75MG do occur. We derive an effective photospheric temperature of HE1045-0908 of T_eff=10000±1000K. The tomographic code makes use of an extensive database of pre-computed Zeeman spectra (Paper I, Euchner et al., 2002A&A...390..633E).
