Astro-Physics Focal Length Reducer 0.67× (Astrophotography)

Compact and powerful, this 0.67× telecompressor significantly increases the speed of your setup.
(reducing exposure time) and shortens focal length. Ideal for RC telescopes
- particularly f/8 models, which are thus reduced to around f/5.3 - and well suited to
refractors around f/9.

  • Reduction factor : 0.67×
  • RC f/8 → f/5.3 about
  • Uncorrected field (focus reduction only)
  • Sensors up to APS-C
  • Optimum backfocus : 85 mm from the thread M48×0.75
  • Sufficient space for OAG and filter wheel
Camera-side thread M48×0.75
Mechanical distance required 85 mm to sensor
Compatibility Refractors ~f/9, RC (ideal f/8)
Field correction No (focus reduction only)
