Tecnosky Extra Flat Field Eyepieces 53°

Tecnosky Extra Flat Field Eyepieces 53°

DESCRIPTION
The Tecnosky Extra Flat Field eyepiece line is designed to deliver a flat, distortion-free image across the entire 53° field of view. Each focal length uses a dedicated optical layout to optimize edge sharpness, especially on challenging optical systems like fast Newtonians or short-focus refractors. Generous eye relief ensures comfort for all users, including eyeglass wearers. The twist-up eyeguard and blackened lens edges improve contrast. All lens surfaces are broadband fully multi-coated (FMC) for maximum light transmission. The housing is finely machined and accepts 1.25" or 2" filters depending on model.
