This essential accessory corrects the curved focal plane of Sky-Watcher EvoStar 150ED refractors, providing a sharp image to the edge of the field. Screwing directly onto the focuser of the telescope thanks to the M56 thread, this reducer/corrector decreases the focal length of the telescope by 0.85x (induced focal ratio of f/6.8), ideal for astronomy and astrophotography, thus reducing exposure time.

  • Backfocus: 55mm
  • Induced focal ratio: f/6.8
