Tecnosky Ultra Flat Field Eyepiece 18 mm 65°

DESCRIPTION
The Tecnosky Ultra Flat Field 18 mm is designed with a new optical formula consisting of 8 elements in 5 groups, all fully multi-coated. It delivers sharp, contrast-rich images with excellent edge correction, even on short focal ratio instruments.

Its 65° apparent field places it in the super-wide class while maintaining precision and minimal distortion. With 20 mm eye relief and a light 206 g body, it is ideal for extended use. Removing the rubber eyecup reveals an M43x0.75 mm thread for attaching compatible accessories.
