Celestron's X-Cel LX 5mm Eyepiece is designed for comfortable near and deep-space astronomical observation. It is built with a 6-element lens configuration, blackened edges, and anti-reflective fully multi-coated optical surfaces to ensure bright and clear high-contrast images with true color transmission across the entire wide 60° field of view. Celestron engineered the X-Cel LX series of eyepieces with a long 16mm eye relief that brings the user's face back from the scope to minimize vibrations caused by contact with the eyepiece. All eyepieces in the series are completely parfocal, making switching eyepieces convenient by not requiring re-focusing. With a 1.25" diameter barrel, it will fit the most common size drawtubes, visual backs, and accessories; and a rubberized collar provides a non-slip grip especially in cold weather and when wearing gloves. The housing is made of a lightweight and durable aluminum alloy with a reflection-limiting matte anodized finish, and a retractable eyecup that extends with a simple twist for comfortable use with or without eyewear.

Celestron X-Cel LX Reviews
Very Good Quality

Rated 5 out of 5

I have several sets of eyepieces. Original TMB, Zhumell Planetary, ED’s, Paradigm, and Baader Hyperion. All these sets give sharp images and I have no complaints. The Celestron Excel lx set is on par with the rest of these eyepieces. Well made and have a quality look of their own. For the price a whole set is really worth it.

question
Can it fit on a celestron astromaster 114eq?
The X-Cel eyepiece range are good quality, reasonably priced, quite wide field eyepieces (60 degree field), and are parfocal or very close to it. In other words they can be changed without having to refocus. I own a whole set.The 5mm will give you 200 magnification with your telescope, a practical maximum for the moon, bright planets, and double stars. The eyepiece has a standard 1.25 fitting and will fit your telescope and there should be no problem in achieving focus. There is good eye relief, so you don't have to jam your eye up against it to get a good field of view. However all this comes at a cost and it is a little bulkier.I would recommend it as your high magnification, but don't overlook a reasonable mid and low magnification eyepieces to complete your set.... and you can always take them with you if/when you upgrade.The fact that the eyepiece is a little

question
Is this eyepiece compatible with the ETX-60AT telescope?
The telescope takes the eyepieces with the mount of a diameter of 1.25 , so that the eyepiece would fit. The telescope's focal ratio is f/5.8. The eyepiece could have a bit too much of a distortion at periphery. But in order to have little of distortion, one has to move to the $100+ eyepieces, so that for buyers on budget the eyepiece could be OK. I have never used the said telescope before, however I do not think there would be a problem with adjusting the eyepiece into the proper focal position (some eyepieces have their focal point away from just behind the eyepiece, and some telescopes do not have enough of travel of the focuser to compensate for that). I'd say that this eyepiece is one of the brightest compared to the premium budget eyepieces out there, so there should not be a problem with absorbing too much light and dark fields.
