CELESTRON Luminos 31mm Eyepiece

The Luminos series eyepieces offer a wide 82º 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 or seven elements (depending on the model) and is fully multi-coated for crisp, sharp views.  All six Luminos eyepieces are parfocal, which means you can switch out eyepieces during observing sessions with little or no additional focusing required.  Overview: Enjoy wide 82º views with Celestron Luminos Eyepieces. Retractable eyecup pops up when you need it, drops down when you don’t. Sturdy anodized aluminum barrels are threaded for filters. A rubber grip keeps the eyepiece securely in your hands, even when it’s cold or you have gloves on.
