We report on new X-ray and optical observations of PSR J2030+4415, a Gamma-ray Pulsar with an Hα bow shock. These data reveal the velocity structure of the bow shock apex and resolve unusual X-ray structure in its interior. In addition the system displays a very long, thin filament, extending at least 5′ at ∼130∘ to the pulsar motion vector. Careful astrometry, compared with a short archival exposure, detects the pulsar proper motion at 85 mas yr−1. With the Hα velocity structure this allows us to estimate the distance as 0.75 kpc.
