These eyepieces are versatile flat field eyepieces with exceptionally high image definition, which is clearly noticeable when observing planets and the Moon.
Patented EMD tempering provides high contrast and prevents disruptive reflections. With a corrected apparent visual field of 52 degrees, these eyepieces are far superior to simpler Plössl eyepieces. Thanks to the argon gas filling, internal fogging is effectively prevented, and there is no need to worry about dust, lens fungus or cleaning fluids infiltrating. The eyepieces are fitted with a watertight seal. This guarantees many years of unquantifiable observation joy using these high-quality eyepieces.
The Explore Scientific 52° LER series stands for the highest level of comfort and quality, paired with an exceptional price-performance relationship.
