A 4.7mm high performance eyepiece from Explore Scientific with 82° field of view and gas filling.

This eyepiece offers features that you have only known from the Explore Scientific 100° eyepieces so far.

Because even this eyepiece with 82° field of view is waterproof and filled with inert gas. This effectively prevents fogging from inside, the ingress of dust and moisture and the formation of glass fungus. Thus, the high-quality multi-layer coating is particularly well protected and durable.

The handling is also easier, because you can easily treat the eyepiece with cleaning fluid and even strong deafness can not penetrate between the lenses. This eyepiece guarantees an unclouded observation experience for many years! Of course, you do not have to compromise on the image quality, because the eyepiece offers through the elaborate design a sharp and high-contrast image across the entire, huge field of view - even on telescopes with a fast aperture ratio.

High-quality types of glass and blackened lens edges together with the EMD multi-layer coating ensure maximum contrast. In addition, a hinged rubber eyecup, a standard filter thread and a conical locking groove in the stainless steel receptacle are standard features of this eyepiece.
