This 1.25-inch eyepiece is argon-filled and waterproof, effectively preventing internal fogging, dust and moisture ingress, as well as the development of fungi on optical surfaces. The high-quality EMD multi-coating ensures maximum contrast and light transmission while providing protection for the premium glass elements. A foldable rubber eyecup allows for comfortable viewing and accommodates both eyeglass wearers and users without vision correction. The stainless steel barrel features standard filter threads and a tapered locking mechanism for secure attachment to telescope focusers.

The blackened lens edges work in conjunction with the multi-coating to minimize internal reflections and enhance contrast during astronomical observations. This eyepiece can be easily cleaned with standard optical cleaning solutions, and the argon gas filling prevents moisture from entering between the lens elements even in heavy dew conditions. The robust construction and protective features ensure long-term optical performance and reliability for demanding astronomical applications. The precise craftsmanship and thoughtful details make this eyepiece a dependable choice for serious amateur astronomers who value consistent image quality and durable performance. The combination of a wide field of view, excellent edge sharpness, and reliable protective features provides optimal viewing conditions for various celestial objects and telescope types.
