Takahashi offers a prism diagonal, of very high optical quality and with a top-of-the-range finish, which will optimise the performance of your lens. The mechanical output is 1.25" (31.75 mm) female barrel, with a clamp ring.
The 1.25 "UltraFlat Field Eyepiece features a high quality standard and a very compact design, which is designed to remove the field curvature at the edge, resulting in a flat, distortion-free image up to the edge of the visible field of view.
