  Determination of pulsar parallaxes and proper motions addresses fundamental
astrophysical questions. We have recently finished a VLBI astrometry project to
determine the proper motions and parallaxes of 27 pulsars, thereby doubling the
total number of pulsar parallaxes. Here we summarise our astrometric technique
and present the discovery of a pulsar moving in excess of 1000 km/s. As an
example of the application of high precision pulsar astrometry we also infer
the identification of 2 pulsars originating from a disrupted binary in the
Cygnus Superbubble.
