The William Optics 0.8x Adjustable Reducer/Field Flattener 61R is designed specifically for the Zenithstar 61 refractor, providing sharper, flatter images across the entire field of view. This optical accessory reduces focal length while correcting field curvature, making it ideal for astrophotography. It is in great condition with some minute specks in the lens, but these have no effect on quality or functionality.
