| Summary:

The Guitar nebula surrounding PSR B2224+65 boasts a pulsar X-ray filament
likely aligned with the local magnetic field. We present new RoboPol stellar
polarization data distributed along the line-of-sight to the pulsar. The
polarizing effect of intervening magnetized dust allows us to extract a model
for the dust-weighted magnetic field. We detect a magnetic field angle
consistent with the filament if the pulsar is located in the more distant zone
of its parallax-estimated distance range.
