Celestron Reducer Lens .7x - EdgeHD 9.25 (OPEN BOX)

Key Features & Specifications:

Unlock wider fields and faster exposures with the Celestron 0.7x Reducer Lens, custom-engineered for the EdgeHD 9.25" Schmidt-Cassegrain telescope. This high-performance accessory reduces your telescope’s focal ratio from f/10 to f/7, significantly decreasing exposure times while preserving the EdgeHD’s hallmark edge-to-edge sharpness and flat-field correction.

Designed with advanced astrophotographers in mind, this 4-element optical system is optimized specifically for the EdgeHD 9.25’s optical path, delivering high contrast, low distortion, and pinpoint stars across APS-C and smaller full-frame sensors. Whether you’re imaging distant galaxies or wide star fields, the reducer lens gives you the speed and flexibility to do more in every session.

With standard SCT threads, it installs easily on the rear cell of your OTA, seamlessly integrating into your imaging train. Rigid construction and premium coatings ensure long-term durability and top-tier performance night after night.
