The 52° LER eyepiece series from Explore Scientific is designed to provide an exceptional viewing experience, no matter what type of celestial object is being observed. These eyepieces are available in several focal lengths, ranging from 3 mm to 40 mm, to cover a wide range of needs, whether for high magnifications or low magnification observations. Their apparent field of view of 52° and multi-element design ensure unmatched image quality, with great sharpness and optimal contrast.

These eyepieces are perfect for glasses wearers thanks to their long eye relief (LER), which ensures unprecedented viewing comfort. Each eyepiece is filled with argon and has a waterproof design, preventing the formation of condensation and the entry of dust, mold, or liquids. The patented EMD coating helps to avoid annoying reflections and improves contrast, even with fast telescopes.
