TS-Optics M68 × 1 extension — 5 mm This M68 × 1 extension adds a manufacturer-specified 5 mm effective length to a threaded optical train.

This M68 × 1 extension adds a manufacturer-specified 5 mm effective length to a threaded optical train.
It connects matching female and male M68 × 1 interfaces. The quoted spacing is the effective contribution when assembled; a protruding male thread is not an additional spacer once it is engaged.
Use it to build the required distance between a corrector and camera, allowing for the camera’s own flange distance and other adapters. It contains no focal reducer or field-flattening optics; changing physical spacing does not itself change the telescope’s native focal length.
