TS-Optics Field Flatteners, Reducers & Coma Correctors

TS-Optics field flatteners and reducers correct the curved field of refractors so stars stay sharp to the edge of the image. The 1.0x Flattener and Field Corrector comes in 2" versions with T2 or M48 threads, keeping the native focal length.

The 0.79x Photoline Reducer Corrector shortens focal length for a wider, faster field, while the 0.5x 1.25" focal reducer suits small-sensor cameras.
