The present focus of the CBELSA/TAPS experiment is on meson-photoproduction off the nucleon using polarized photons and polarized targets. Here first preliminary results on the reactions γ~→p~→→ pπ~0 and γ~→p~→pη for both circularly and linearly polarized photons and a longitudinally polarized target are presented. Preliminary results for the beam asymmetry Σ and the double polarization observable G have been extracted for both reactions using the linear polarization data. From the circular polarization data the observable E has been determined. Due to the near 4π angular coverage of the detector system these results cover almost the full solid angle.
