Celestron Ultima LX 5mm Eyepiece Product Info

The Ultima LX series eyepieces offer a wide 70º field of view in both high power and low power models, allowing you to make the most of your telescope, whether you own a short, fast refractor or a Celestron EdgeHD telescope. The optical set consists of six-to-eight elements (depending on the model) and is fully multi-coated for crisp, sharp views. All six Ultima LX eyepieces sport an eye relief of 16 mm, and are parfocal, which means you can switch out eyepieces within the series during observing sessions and little or no additional focusing will be required.

The Ultima LX eyepiece body consists of a rubber-coated surface, similar to many binocular models. A rubber coating offers shock resistance as well as a non-slip grip. Contours dimpling the surface add to the slip resistance, and keep the eyepiece from rolling to the floor when placed on a flat surface. The pop-up eyecups are a nice feature as well. Turn them in one direction to extend the length, and the other direction to provide a flat surface, preferable to most eyeglass wearers. The insert barrel, whether 2” or 1.25” is threaded to accept filters.
