CELESTRON E-LUX EYEPIECE 2" 40mm
Celestron
CELESTRON E-LUX EYEPIECE 2" 40mm is backordered and will ship as soon as it is back in stock.
The Celestron E-Lux 40mm 2" 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 that is machined from high grade aluminium with a black anodized outer surface. The internal surface of the mounting barrel has been machined with light dispersion threads that are 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 wearers and non-eyeglass wearers alike, thanks to the rubber eyecups and long eye relief of 36mm.
