The EdgeHD .7x Reducer Lens significantly enhances the capabilities of your EdgeHD 9.25" telescope, effectively making it one full F-Stop faster than f/10. This remarkable feature not only halves your exposure time for capturing objects with the same brightness but also expands your field of view by 43%, making it ideal for wide-field imaging.

Key Features:

1. Optical Excellence: The 4-element lens design maintains the native flat-field performance of the EdgeHD optical system, offering crisp and clear images.

2. Advanced Lens Elements: Incorporates high-quality Lanthanum glass elements for high-contrast viewing with minimal chromatic aberration. All lens elements have fully multi-coated surfaces for enhanced light transmission and color accuracy, and blackened edges to reduce internal reflections.

3. Large Aperture: The clear aperture of 60mm is optimized for a 42mm image circle, accommodating large CCD sensors and ensuring comprehensive image coverage.

4. Precise Mechanical Construction: The reducer is built with a CNC machined aluminum housing for exact spacing and alignment of optical elements. Threaded metal covers protect both ends of the lens assembly, safeguarding your investment.

5. Flexible Compatibility: Threads directly onto the 3.25" threads of the EdgeHD, reducing mechanical vignetting and enabling use with larger full-frame sensors and Off-Axis Guiders. It supports the use of existing EdgeHD T-Adapters, both with and without the reducer lens.

6. Versatile Imaging Options: Compatible with Fastar/hyperstar systems for f/2 imaging, the EdgeHD with the .7x reducer offers a comprehensive imaging system for a range of astrophotography applications.

The Celestron EdgeHD .7x Reducer Lens for the 9.25" model is a crucial addition for any astrophotographer looking to enhance their capabilities, offering a perfect blend of speed, field of view, and optical fidelity.
