- The EdgeHD .7x Focal Reducer Lens makes your EdgeHD 9.25" one full F-Stop faster than f/10, reducing your exposure time by half to capture the same brightness of object
- 4-element lens design
- Maintains similar flat-field performance as native EdgeHD optical design
- Increases field of view by 43% to better capture wide field images
- Threads directly onto the 3.25" threads of the EdgeHD which reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders

- Allows use of existing EdgeHD T-Adapters with or without the Reducer Lens
