Tecnosky 0.8× Field Flattener/Reducer for APO 115/800 mm

Tecnosky 0.8× Field Flattener/Reducer for APO 115/800 mm

Overview

The Tecnosky 0.8× Reducer/Flattener is designed for 115 mm aperture, 800 mm focal length apochromatic refractors. It reduces the focal length by 20%, increasing brightness and field of view, while correcting field aberrations for sharp images across the frame.

Compatible with full-frame sensors, it offers a corrected field of 42 mm. It threads directly onto 3" focusers with M68x1 mm threads and connects to cameras via M48x0.75 mm threads.
