Product description

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.

Review by M. G. on 26.07.2022 21:54:53

It is fantastic eyepiece if you want to concentrate on one object in a detail. The FOW is sufficient and the whole M13 fits within it. M13 is very well resolved into individual stars and the object is still bright enough. M57 was also well defined. Saturn was too low above the horizon, but still nice with the gap in the ring visible and with multiple moons visible. Double stars such as Eta Lyrae's tight components AB and CD were resolved with this eyepiece. It's very well manufactured.
