Description

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 56° apparent field of view. The 40mm E-lux eyepiece's very low power is perfect for those times when you need all the light-gathering your telescope can offer to see faint deep-sky objects.

This 40mm 2" E-lux eyepiece is offered a la carte, but it is also included in the2" Eyepiece and Filter Kit.If you are looking for multiple Kellner eyepieces, filters, and a Barlow, we recommend the 2" Eyepiece and Filter Kit.

Body

The 40mm E-Lux eyepiece has a main housing that is machined from high grade aluminum 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.

Isabella ★★★★★

Finally got this 40mm for my 2" focuser and the 56° apparent field really opens up the view on larger objects like the Andromeda galaxy. The fully multi-coated optics give a nice, crisp image without any glare. I'm thrilled with how much more of the sky I can take in now.

Daniel ★★★★★

The 56° field of view is fantastic for sweeping the Milky Way, and the 36mm of eye relief means I can see the whole thing even with my glasses on. Views through my 2" focuser are crisp and bright.

Victoria G. ★★★★★

I was worried about eye relief being an issue with my glasses, but this 36mm eyepiece lets me see the whole field without any blackouts. Jupiter’s moons are crisp and clear right to the edge of that 56-degree view.
