Product Description
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.
The Luminos eyepiece body is made of polished and anodized aluminum. A rubber grip runs around the equator of the eyepiece, giving you a secure grip and an easy method for raising and lowering the retractable eyecup. Simply twist the rubber grip to adjust the height of the eyecup. The insert barrel is threaded to accept filters.

Customer Reviews
This eyepiece is very large but the view is sharp clean with no noticeable chromatic aberration . Also the eyepiece does not show any bend of the field of view even in the extreme corners to my eyes. This is when it is tested during the day looking outside and at night at the night sky. This is not a lens camera test against square boxes searching for imperfections my observation is simply based on the original intendent use as an eyepiece for human observation. The eyepiece require some getting use to because of the very large field of view but this is normal for all wide angle eyepiece.
I would recommend the product if you need this specific focal length it is a good purchase buy.
