Lens .66x Reducer

SKU: 600166 Categories: ,

$1,400.00

The PlaneWave 0.66x Reducer is engineered specifically for flat-field telescopes like the CDK20 or CDK24, optimizing focal length for enhanced imaging capabilities. This model, designed for use with the IRF90 rotating focuser, features a low-profile build to accommodate cameras that require extra back focus. While the reducer itself has minimal back focus, it does utilize a substantial portion of the telescope’s overall back focus, so precise spacing is essential. When paired with a compatible camera, this reducer decreases the CDK’s focal ratio while maintaining top-tier optical performance.

IRF90 – Integrated Rotating Focuser
  • The IRF90 is a large capacity Integrated Focuser and Rotator for use with Alt/Az, or equatorially mounted systems.
  • Occupies 3.5″ of backfocus with the focuser fully racked in, and 4.7″ when fully racked out.
  • The Focuser is capable of lifting 40 lbs (18 kg) with a range of 30mm (30000 microns/1.2″).
  • The Rotator has a 90mm aperture with a range of 365 degrees with hard stops to eliminate any chance of cord wrap.
  • IRF90 is controlled via PWI4 software for autofocusing and optional field de-rotation (if using an Alt/Az mounted system).
