A sample of high-luminosity supergiants observed with AF2. All these objects suffer moderately high to high extinction, as indicated by the 8620 Å DIB blended with Fe i 8621 Å. All these objects have radial velocities similar to members of Ste 2, except 18395861−0549549, which has a slightly lower v_rad. The strength of the 8514 Å feature compared to the neighbouring Ti i 8518 Å is an indicator of high luminosity.
