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

The eyepieces are equipped with waterproof sealing. This guarantees many years of incomparable enjoyment when observing using these high-quality eyepieces.

The Explore Scientific 52° LER series represents the highest level of comfort and quality, combined with an excellent value-for-money ratio.
