TS-Optics REFRACTOR 0.79x 3" ED Reducer Corrector for large sensors"

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