Providing performance at a reasonable price for most beginners, the Celestron E-Lux 40mm Kellner Eyepiece produces low power in most telescopes. It is designed to be a perfect addition to your observation arsenal when you want to take in large portions of the sky for comet hunting, viewing nebulae, or exploring all the stars in a constellation.
Outfitted with a generous 56° apparent field of view and treated with anti-reflection multicoatings that produce bright and clear wide-angle views. This model of the E-Lux is offered here with a large 2" barrel that allows the maximum amount of light to pass through to the eye with a long 36mm eye relief for a more comfortable observational experience with greatly reduced eyestrain and fatigue. A textured collar provides a slip-resistant grip, especially in cold weather or while wearing gloves, and the fold down rubber eyecup makes it comfortable and easy to view through, with or without eyeglasses.
