Comment (by Stephan66):

 This comment on the subject was posted by user Ines Schwarzbach on the
 Qgis forum:

 The solution with the Stereographic projection

 +proj=stere

 works fine at me, too.

 But I think there is a difference between Oblique stereographic projection
 +proj=sterea and
 a "simple" Streographic projection with +proj=stere.

 I've tested this parameters with the proj4 command cs2cs and there are the
 following results:

     cs2cs +proj=sterea +lat_0=34.2 +lon_0=39.15 +k=0.999534
 +x_0=281796.701 +y_0=28040.358 +a=6378249.2 +b=6356515 +units=m +no_defs
     +to +proj=latlong +datum=WGS84
     9657.511 10507.357
     36d12'10.22"E 34d0'23.232"N 0.000



     cs2cs +proj=stere +lat_0=34.2 +lon_0=39.15 +k=0.999534 +x_0=281796.701
 +y_0=28040.358 +a=6378249.2 +b=6356515 +units=m +no_defs
     +to +proj=latlong +datum=WGS84
     9657.511 10507.357
     36d12'10.1"E 34d0'23.823"N 0.000



 The differences are quite large. So the problem still exists.
