## 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.

Review: It's so Big, but it's so Good! - What can you say about Luminos eyepieces? First impression, they are big and heavy. Lots of glass and metal that could put you over the limit on your mount if you are already close, but so worth the view! I now own the 31mm, 23mm, 19mm, and 15mm Luminos eyepieces. For the money they are a great value, exceptionally built with outstanding wide, clear, bright views, and convenient features like the adjustable eyecup. Luminos is not TeleView good, but what is? Luminos holds it's own at its given pricepoint and is a great value. Using with a Celestron CPC 925 Edge HD.
Review: Outstanding Eyepiece! - It would be difficult to overstate how wonderful this eyepiece is. It IS enormous (roughly the size of a softball) as other reviewers have pointed out, but the clarity is outstanding. It offers a wide view of the sky making it easy to find objects, even if you're slightly off on your finder. It also offers the most beautiful view of the moon I've seen. It fills your view yet provides incredible detail. I could not be happier with this eyepiece.

### ⭐⭐⭐⭐ The Moby Dick of eyepieces
*by D***N on March 11, 2015*

As many have noted, this is about the largest eyepiece you could possibly imagine. I knew it was big from other reviews, but I admit I started laughing out loud when I actually took it out of the box. The eyepiece is about the size of a softball, and seems to weigh just a tad less than a bowling ball. That said, there is nothing to hate about its optical quality. My eyepiece is crystal clear, sharp, and offers a stunning wide-angle view of the sky. I am more than pleased by it. However, any telescope user needs to consider the size and weight of this eyepiece. It may throw off the balance of your scope quite easily. But honestly, if you can deal with that you will be more than happy with its optical performance.
