We utilize STEREO quadrature observations to study two CMEs that both originated from high-latitude source regions on 2 November 2008. The first CME was associated with a huge polar crown filament eruption and propagated initially clearly northward from the equator. However, the CME was quickly deflected towards the equator while propagating further out. On the other hand, the second CME, originating from an active region, did not deflect from its original northward trajectory. Based on the observations we discuss the role of the size of the erupting structure and the magnetic topology of the surrounding environment in deflecting CMEs and suggest that both a breakout initiation scenario as well as a tether-cutting initiation scenario can explain the observed deflective dynamics of the filament eruption.
