.7x Focal Length Reducer for EdgeHD 9.25” : Optimize your Astrophotography Performance
Enhance your telescope's capabilities EdgeHD 9.25” with Celestron's .7x focal reducer. Designed specifically for this model, it combines speed, exceptional optical quality and versatility to transform your astrophotography sessions.
Superior performance
- Increased speed: f/7 - Reduce the focal ratio from f/10 to f/7, speeding up exposure times by half while maintaining optimum brightness for professional-quality images.
- Enlarged field of view by 43 % - Ideal for capturing large galaxies, nebulae and star clusters in a single shot.
- 4-element optical design - Keeps the field flat and corrects optical aberrations, guaranteeing sharp, distortion-free images.
Advanced Optical Technology
- High-end Lanthane glass - Lanthane «rare earth» glass elements minimize chromatic aberrations while delivering exceptional contrast, perfect for images rich in detail.
- Multi-layer treatments - Each air-glass surface is multi-coated for maximum light transmission and precise color correction.
- Blackened edges - Eliminate internal reflections, increasing contrast and delivering sharper images.
- Clear 60 mm opening - Optimized for a 42 mm image circle, compatible with full-frame CCD sensors.
Robust mechanical design
- Direct attachment to 3.25" EdgeHD tube threads - Ensures maximum compatibility with large-format sensors and accessories such as off-axis guides.
- CNC-machined aluminum body - Ensures precise spacing and perfect alignment of optical elements for optimum performance.
- Threaded metal covers - Protect lenses from dust and scratches, ensuring long-term durability.
Exceptional versatility
- Retention of native back-focus - The reducer maintains the same back-focus as at f/10, enabling the use of a wide range of accessories and cameras. Compatible with existing T EdgeHD adapters.
- Fastar compatibility - Combine it with the Fastar system for ultra-fast imaging performance at f/2, ideal for capturing faint objects with reduced exposure time.
