Explore Scientific Eyepiece 82° LER AR 8.5mm 1.25"

Explore Scientific’s 82° range introduces LER eyepieces, broadening their selection of argon-filled and waterproof models to accommodate users with larger pupillary distances. The common issue among glasses wearers, unable to view the entire visual field with shorter focal length eyepieces, is now resolved with the inclusion of foldable silicone eyecups, ensuring optimal comfort with or without glasses.

These eyepieces redefine the viewing experience, offering exceptional flat field performance. Patented EMD tempering ensures high contrast and eliminates disruptive reflections. Notably, they provide exceptionally high image definition, particularly evident when observing planets and the Moon.

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

With a highly corrected apparent visual field of 82°, these eyepieces offer exceptional quality. Thanks to the argon gas filling, internal fogging is effectively prevented, and concerns about dust, lens fungus, or cleaning fluids are eliminated. Equipped with a watertight seal, these eyepieces ensure years of unparalleled observation joy. The Explore Scientific 82° LER series embodies top-tier comfort and quality, offering an exceptional price-performance ratio.
