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 provides the much-mentioned spacewalk experience. Thanks to their particularly flat field of view, stars remain pinpoint-sharp even at the edges, making these eyepieces an excellent choice for use with faster telescopes. The eyepieces offer above-average eye relief, ensuring exceptionally high viewing comfort.
A distinctive feature of these eyepieces is their waterproof construction, which makes the internal components particularly resistant to fogging. The effective anti-reflection coatings on the lens surfaces and the matte-black finish of the internal surfaces ensure outstanding contrast and protection against reflections. Each eyepiece is individually serial numbered.
