  The light propagation in plasma medium around stationary gravitating objects
is studied in the geometrical optics limit. Static metrics with quadrupole
moments are considered, however, the main attention is paid to the stationary
Hartle-Thorne metric and Kerr metric. Their different effects on the light
deflection are compared. The deflection angle is given in a general analytic
form, the detailed calculations are performed in the weak field limits and
illustrated graphically. The trajectories of the light rays are constructed and
compared, emphasizing the role of the quadrupole moment.
