Explore Scientific 82° Series eyepieces offer premium quality at a surprisingly affordable price. Compared to earlier models with similar focal lengths, the new LER series features slightly increased eye relief.
The 82° apparent field of view creates the much-discussed spacewalk effect. Thanks to their particularly flat field of view, stars remain sharp right to the edge, making these eyepieces an excellent choice even for use with faster telescopes. Their above-average eye relief provides outstanding viewing comfort.
A distinctive feature of these eyepieces is their waterproof construction, which makes the internal components particularly resistant to fogging. Efficient anti-reflection coatings on the lens surfaces and matte-black internal surfaces ensure exceptional contrast and protection against reflections. Each eyepiece is individually serial numbered.
