Excellent ultra-wide angle eyepiece with 82° apparent field of view
Thanks to the complex optical system consisting of 7 lenses arranged in four groups, sharp and bright imaging performance is guaranteed across the entire field. In addition, a multi-coated FMC coating on all lens surfaces prevents reflections.
Tecnosky is thus expanding its range of eyepieces with four ultra-wide-angle eyepieces with an apparent field of view of 82° in focal lengths of 4.7, 16 and 28 mm. These eyepieces work very well even in fast (light-gathering) telescopes and at high magnifications. The FMC coating and uniform internal blackening eliminate all unwanted reflections. The eyepiece barrels are made of aluminium and have a non-slip rubber armouring. In addition, the eye relief can be individually adjusted using a rotating "twist-up" eyecup.
The eyepieces with focal lengths of 4 mm, 7 mm and 16 mm have a 1.25" barrel. The 28 mm eyepiece is 2".
