Explore Scientific Eyepiece 82° LER AR 4.5mm 1.25"

Explore Scientific's 82° range introduces LER eyepieces tailored for those requiring larger pupillary distances, offering a solution for glasses wearers who often face challenges viewing the entire visual field with shorter focal length eyepieces. Equipped with foldable silicone eyecups, these eyepieces ensure optimal user comfort, accommodating both glasses and non-glasses users alike.

These exceptional flat field eyepieces redefine your viewing experience, boasting patented EMD tempering for high contrast and minimal disruptive reflections. Notably, they excel in delivering exceptionally high image definition, particularly evident when observing planets and the Moon.

Designed for high performance, these eyepieces with short focal lengths (ranging from 3mm to 10mm) are not limited to lunar, planetary, and binary star observations but also excel in revealing bright, compact deep sky objects. Impressively showcasing planetary nebulae and globular clusters against a very dark background sky, they elevate contrast effectively at higher magnifications. However, clear images at such magnifications demand good to excellent atmospheric conditions.

Featuring a highly corrected apparent visual field of 82°, these eyepieces ensure exceptional quality. Argon gas filling effectively prevents internal fogging, safeguarding against dust, lens fungus, and cleaning fluid infiltration. Complete with a watertight seal, they promise years of unparalleled observation joy. The Explore Scientific 82° LER series epitomizes top-tier comfort and quality, delivering an exceptional price-performance ratio.
