This Explore Scientific 4.5 mm LER Waterproof Eyepiece - 82 Deg - 1.25" size is one of the series of great Long Eye Relief 82° AFOV Argon purged Waterproof Eyepieces from Explore Scientific. This series is aimed at comfortable viewing for all. The long Eye Relief is better for astronomers who wear glasses, as well as all other astronomers. This eyepiece’s 4.5 mm focal length can produce high magnifications that excel for observing objects like the Moon, the planets, and binary stars. When atmospheric conditions are almost perfect, this eyepiece can enhance planetary details and allow for thorough explorations of the structures within deep sky objects like nebulae.
This multi-element eyepiece achieves superior light transmission with edge-blackened optics made of low-dispersion glass with a high refractive index. Each lens also is fully multi-coated with durable enhanced multi-layer deposition (EMD) coatings. These manufacturing specifications assure the best performance from your telescope to capture celestial images you expect with sharp contrast, high resolution, and crisp definition.
The ultra-wide 82° apparent field of view opens up a wide view (AFOV) from your telescope and naturally promotes relaxation at the eyepiece. When you relax your eyes and take in the scene presented before you, it is much easier to observe for longer periods of time, and details begin to materialize. This effect also promotes the use of averted vision at the eyepiece, which allows your eye to see and recognize fainter images. In addition, this series of eyepieces are all waterproof and Argon gas purged with O-ring seals. This technology keeps your eyepieces free from dust, fungus, and fogging, and makes cleaning them very easy and safe.
