This accessory is necessary because refractors (binoculars) provide a curved focal plane, stars are not pinpoint near the edges. The reducer/corrector provides a corrected image up to the edge of the field.
Characteristics
- Reduction ratio: 0.85x (induced focal ratio of f/7.65)
- Threads: Female M56 at the front, male M48 at the rear
- Backfocus: 55mm
The use of a focal reducer in astrophotography also allows to reduce the exposure time. It will be necessary to use a dedicated wide field T ring M48 for your camera.
Warning: Not suitable for Sky-Watcher ESPRIT 100ED (triplet) binoculars.
