There remain several definitive γ-ray pulsars that are as yet
undetected in the optical regime. A classic case is the pulsar PSR B1951+32, associated with the complex CTB 80 SNR. Previous ground
based high speed 2-d optical studies have ruled out candidates to
. Hester (2000a) has reported an analysis of archival
HST/WFPC2 observations of the CTB 80 complex which suggest a compact
synchrotron nebula coincident with the pulsar's radio position.
Performing a similar analysis, we have identified a possible optical
counterpart within this synchrotron nebula at 
, and
another optical counterpart candidate nearby at 
. We
assess the reality of these counterpart candidates in the context of
existing models of pulsar emission.
