The Glaspath Correctors were designed primarily to correct the prismatic color fringing that occurs with refractors due to the high amount of glasses used in binocular prisms. The Glaspath Correctors are not Barlow lenses. The reason for this name is only secondly the displacement of the focal point.
Several versions are available for the Baader Mark V Binocular viewer. The BP4A version is included with your Mark V binocular viewer.

Optical path length: >= -30mm

BPRSBC18 - 2" Refractor/Schmidt Cassegrain Corrector at full aperture 1:1.8x
