The TS Optics PHOTOLINE 0.79x reducer / corrector
...has been designed for astrophotography through APO refractor telescopes. It makes the system faster and corrects for the field curvature even with full size sensors. It does not need the extreme back focus of the Riccardi corrector. It is suitable for all models with focusers from 2.5" and connects to them via M68 thread or 3" barrel.

Question:
How do you have to measure the working distance?

Answer from Teleskop-Service:
The working distance is measured from the beginning of the connection thread on the housing of the corrector (see example picture):
