Using the fact that the null geodesies in NUT space lie on spatial cones, we consider the gravomagnetic lens effect on light rays passing an NUT deflector. We show that this effect changes the observed shape, size and orientation of a source. Compared with the Schwarzschild lens, there is an extra shear (a differential twist around the lens axis) due to the gravomagnetic field which shears the sha...
