The 52° LER eyepiece series from Explore Scientific is designed to provide an exceptional observing experience, regardless of the type of celestial object 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 eyeglass wearers thanks to their long eye relief (LER), which ensures unprecedented observing comfort. Each eyepiece is filled with argon and features a waterproof design, preventing the formation of condensation and the ingress of dust, mold, or liquids. The patented EMD coating helps avoid troublesome reflections and enhance contrast, even with fast telescopes.
