Diagonal prism with quick-release fastener 2"

The BK 7 glass diagonal prism offers maximum accuracy and image brightness thanks to the new ultra-wideband coating.

The sturdy housing is precision CNC-milled. The accessories are held securely in place with quick-release clamps. The 2" accessories on the eyepiece side are held in place over the entire surface by a ring clamp. Unlike clamping screws, this ensures that the eyepiece or adaptor is centred exactly on the optical axis and is not pressed against the opposite surface.
