The 13 mm Tecnosky XWA is an extra-wide-angle eyepiece with an apparent field of view of 100°.
The incredibly wide field of view is ideal for observing large deep sky objects - with an 80mm triplet refractor, for example, you get a real field of view of 2.7°!
Thanks to its high optical quality, it also offers excellent performance with the Moon, Sun and planets.
The eyepiece barrel, which contains the complex 9-element optical system, is made entirely of aluminium and has a 31.8 mm and 50.8 mm connection. The removable eyecups allow you to make the most of the comfortable 15 mm eye relief and the corrected field of view. The interior of the eyepiece is filled with nitrogen to permanently prevent the formation of condensation and mould.
