Reducer / Corrector 0.85x Sky-Watcher for 80ED - Sky-Watcher

This accessory is necessary because refractors (binoculars) provide a curved focal plane, stars are not punctual near the edges. The reducer/corrector provides a corrected image to the edge of the field.

Characteristics

• Threads: Female M56 at the front, male M48 at the back
• Backfocus: 55mm

Advantages

The use of a focal reducer in astrophotography also allows to reduce the exposure time. It will be necessary to use a dedicated large field T-ring M48 for your camera.

Caution: Not suitable for Sky-Watcher ESPRIT 80ED (triplet) binoculars.
