Description

Enhance your astrophotography results with the Orion 0.8x Reducer for the EON 115 mm Refractor. This dedicated reducer and field flattener improves image quality by correcting field curvature and delivering sharp stars across the entire frame, even with full-frame sensors. By reducing the focal length by 20%, it creates a wider field of view and brighter images while enabling shorter exposure times. Designed specifically for photographic use, it threads securely onto the focuser for a stable, flexure-free connection, making it an essential upgrade for capturing detailed deep-sky images.
