Field Flatteners & Reducers
Field flatteners and reducers are optical accessories designed to improve image quality in astrophotography. Field flatteners correct edge distortion for sharper, even star fields, while focal reducers widen your field of view and boost light-gathering speed. Ideal for visual observers and astrophotographers pairing refractors or reflectors with cameras or eyepieces.
