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.
