Description:
   From an ultra-low dispersion spectroscopic survey of the Cyg OB2 association
   several red and reddened stars are detected. Most of these stars appear to
   be reddened early-type stars belonging to the Cygnus OB2 association. The
   distance moduli V_0_-M_v_=11.2 and minimum reddening E(B-V)=1.2 suggests that
   some of the red stars in the magnitude range 15 to 17 are most likely
   reddened late B and early A main sequence stars of the Cyg OB2 association.
