- Compatible with PlaneWave CDK20 & CDK24 OTAs and IRF90 rotating focuser
- Reduces the focal ratio by 66% so you can capture brighter and more contrasted images faster
PlaneWave 0.66x Reducer for CDK20 & 24 OTAs (IRF90 Optimized)
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.
