Descrição: In this short-note, I have discussed spherical deformation in rotationally perturbed spacetime which is valid for strong gravitational fields assuming star is homogenous and spherically symmetric. I have considered a photon emitted by a rapidly rotating star (pulsar) and calculated net deflection angle. In this case, we observed that rapidly emitted photon has shown bending under inertial frame drag effect which is opposite to non rotational case. I have also considered red-shift effect in this situation and observed that the red shift of a line emission shifted towards lower frequency with the effect of broadening. The rotation effect is also maximum on tangentially backward emitted photon which causes limbs of the stars moves away from observer
