.7x EdgeHD focal reducer for 11": Capture More, Faster
Transform your EdgeHD 1100 into a high-performance astrophotography tool thanks to Celestron's .7x focal reducer. Designed specifically for the EdgeHD 11" system, this reducer gives you unrivalled speed and versatility, while preserving the exceptional flat-field quality characteristic of the EdgeHD series.
Improved Optical Performance
- Increased speed: f/7 - Switch from f/10 to f/7 focal ratio, a full stop gain. This cuts your exposure times in half to capture celestial objects with identical brightness.
- Enlarged field of view by 43 % - Ideal for capturing galaxies, nebulae and other extended celestial objects with enhanced precision.
- 5-element optical design - Maintains a flat field and corrects optical aberrations for sharp, detailed images across the entire sensor.
High-End Optical Technology
- Rare earth" lanthanum glass - Lanthane glass elements minimize chromatic aberration and deliver exceptional contrast, ideal for precise, detailed images.
- Multi-layer treatments - The air-glass surfaces are fully multi-layered to maximize light transmission and ensure optimum color correction.
- Blackened edges - Reduce internal reflections to optimize contrast and eliminate parasitic effects.
- Clear 60 mm opening - Optimized for a 42 mm image circle, perfectly suited to large, full-format CCDs.
Robust mechanical design
- Direct attachment to 3.25" EdgeHD tube threads - Eliminates mechanical vignetting and allows the use of full-format sensors and off-axis guides.
- CNC-machined aluminum body - Ensures precise spacing and perfect alignment of optical elements for optimum quality.
- Threaded metal covers - Protect lenses from dust and scratches, guaranteeing long life.
Versatility and compatibility
- Retention of native back-focus - The reducer preserves the same back-focus as at f/10, offering full compatibility with a wide range of accessories and cameras, as well as with existing T EdgeHD adapters.
- Fastar compatibility - Combine the Fastar system with the reducer for impressive imaging speed at f/2, ideal for capturing faint objects in record time.
- Ready for full-format sensors - Optimized for large sensors, with no noticeable vignetting.
