SVBONY Field Flatteners, Reducers & Coma Correctors

SVBONY correctors and reducers adjust the focal length and field of a telescope for imaging or visual use. The SV193 0.8x reducer/flattener in 2" shortens the focal length while flattening the field for camera sensors, and the SV209 1.0x flattener is matched to the SV550 80mm f/6. Two 1.25" 0.5x focal reducers screw onto cameras or eyepieces for a wider view.

The SV199 ADC corrects atmospheric dispersion on planets low in the sky.
