.7x EdgeHD Focal Length Reducer for 14": Accelerate Your Astrophotography
Transform your EdgeHD 1400 into a faster, more powerful imaging machine with Celestron's .7x focal reducer. Designed specifically for the EdgeHD optical system, this reducer offers an unrivalled combination of speed, extended field of view and impeccable optical performance, while maintaining the iconic flat field of the EdgeHD series.
Advanced Optical Performance
- Reduced to f/7
- Switch from f/11 to f/7 focal ratio, a full stop gain, cutting your exposure times in half while capturing the same luminosity.
- Enlarged field of view by 43 %
- Ideal for capturing wide-field images of galaxies, nebulae and other extended celestial objects.
- 5-element optical design
- Keeps the field flat and corrects aberrations for sharp, detailed images, even at the edges of the field.
Advanced Optical Technology
- Lanthanum glass elements
- Uses "rare-earth" glass for high-contrast images, while minimizing chromatic aberrations.
- Multi-layer treatments
- All air-glass surfaces benefit from multiple coatings for maximum light transmission and optimum color correction.
- Blackened edges
- Reduces internal reflections and improves image contrast.
- Clear 60 mm opening
- Optimized for a generous 42 mm image circle, perfectly suited to large, full-format CCDs.
Robust mechanical design
- Direct attachment to 3.25" threads on EdgeHD optical tube
- Reduces 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.
- Threaded metal covers
- Protect the gearbox from dust and scratches for longer life.
Versatility and compatibility
- Native back-focus maintained
- The reducer retains the same back-focus as at f/11, enabling the use of a wide range of accessories and cameras, as well as existing T EdgeHD adapters.
- Fastar compatibility
- Combine the Fastar system with the reducer for a complete, fast imaging experience at f/2, ideal for capturing faint objects with ultra-short exposure times.
- Ready for full-format sensors
- The wide-angle design ensures perfectly illuminated images, without noticeable vignetting, even with large sensors.
