Explore Scientific Eyepiece 82° LER AR 6.5mm 1.25"

Explore Scientific expands their range of argon-filled and waterproof eyepieces with LER eyepieces from their 82° series, designed specifically for users with large pupillary distances. Often, glasses wearers encounter difficulty viewing the entire visual field with shorter focal length eyepieces, but this issue is now a thing of the past. The inclusion of foldable silicone eyecups ensures optimal user comfort, whether wearing glasses or not.

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.
