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 up to the edge of the field.

Characteristics

  • Threading: Female M56 at the front, male M48 at the rear
  • Backfocus: 55mm

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

Optimized for Sky-Watcher EvoStar 150ED f/8 (Doublet) binoculars, this screw-in reducer/corrector reduces the focal length of the binocular by a factor of 0.85x (induced focal ratio of f/6.8).

Warning: Not suitable for Sky-Watcher ESPRIT 150ED (triplet) binoculars.
