Tecnosky 13mm HD Super Wide Angle 70° 31.8mm (1.25") Eyepiece

Tecnosky expands its eyepiece range with a series of 70° field SWA eyepieces featuring an 8-element optical design, including one ED glass element.
All lenses are blackened at the edges and feature FMC anti-reflective coating to eliminate any unwanted reflections.
The complex optical design ensures excellent chromatic and geometric correction across the entire field.
Due to the sharpness and contrast they are capable of delivering, we recommend them for both high-magnification observation and deep-sky viewing.
The mechanical components are manufactured using CNC machines and finished with a hard black anodization.
All eyepieces (except for the 22mm and 32mm) feature a dual-size barrel for both 31.8mm and 50.8mm.
Furthermore, by unscrewing the upper rubber eyecup, it is possible to access a 43x0.75mm thread which, when coupled with a Baader Hyperion adapter ring, becomes a standard T2 (42x0.75) thread compatible with cameras and CCDs for projection photography.
