These eyepieces are versatile flat-field eyepieces with exceptionally high image clarity, which is clearly noticeable when observing planets and the Moon.

The patented EMD processing provides high contrast and prevents annoying reflections. With a corrected 52-degree optical field, these eyepieces are much superior to simpler Plössl eyepieces. Thanks to argon gas filling, internal fogging is effectively prevented, and you don't have to worry about dust, lens fungi, or cleaning liquids penetrating.

The eyepieces are equipped with water-tight sealing. This guarantees many years of invaluable enjoyment of observation using these high-quality eyepieces. The Explore Scientific 52° LER series represents the highest level of comfort and quality, combined with an excellent price-performance ratio.
