The visual effect of these new 4.5 mm 82° LER eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the “averted vision” technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with foldable eyecups make handling and using in the field easy.
As experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves.
These eyepieces are the choice for observers wearing glasses – with excellent performance and durability. The patented EMD”-coating produces high contrast images and prevents reflexes and ghosting. The argon purging effectively prevents internal fogging, and you don´t have to deal with dirt, fungus or cleansing fluids getting between the lenses. The eyepieces are sealed – this makes sure you will be able to enjoy these eyepieces for many years to come.

These extreme wide field eyepieces are optimized to produce high contrast and high resolution characteristics.
