Celestron 2" 40mm E-Lux Eyepiece
Celestron E-Lux eyepieces provide a very sharp central area and are best suited to telescopes with long focal lengths.
Get more light to your eye and enjoy the low-power, wide-field views of Celestron’s E-lux 2” eyepiece. Designed to be used with any telescope with a 2” focuser, the Celestron E-lux eyepiece is a 3-element, fully multi-coated Kellner design with a 56º apparent field of view.
The 40mm E-Lux eyepiece has a main housing machined from high-grade aluminium with a black anodised outer surface.
The internal surface of the mounting barrel has been machined with light dispersion threads painted matte black to cut down on internal reflections for a clear viewing experience.
Viewing through the E-lux eyepiece is comfortable for both eyeglass and non-eyeglass wearers, thanks to the rubber eyecups and long eye relief of 36mm.
