Celestron engineered their Luminos 7mm Eyepiece to provide you with a comfortable 82° field of view, and made the entire series parfocal, allowing you to change it out with other Luminos eyepieces without having to adjust the focus. This allows you to spend more time viewing while reducing the chance of hitting the scope out of alignment. This model features a 7-element lens configuration and is fully multi-coated to improve image brightness and contrast. Its 1.25" diameter barrel fits the same size drawtube or accessories, and has machined filter threads to accept eyepiece filters. Made of a lightweight and durable aluminum alloy with an anodized finish, the body has a slip-resistant rubber collar, and an innovative retractable eyecup that pops up when you need it and drops down when you don't with a simple twist.

Celestron Luminos Reviews
Nice eyepiece for multiple star systems.
It will fit 3 or more stars orbiting each other into its field of view. Orion's 4 star Sigma Orionis, which has more than 4 stars in orbit, but are too close and too dim to its main giant blue star to see. Like the brightest star in the night sky not a planet is Sirius in Canis Major. Its binary is too close to ever see without an observatory quality telescope. Be that as it may this eyepiece is excellent for looking at star clusters and view the amount of stars in the wide field of view. I use it on globular star clusters. For close ups of the Moon it cannot be beat when conditions are good. I also use it with the Luminos 2.5x Barlow to for close ups of planets and Comet 12P/Pons-Brooks.
Precision
Heavy in a good way. Quality and nice wide field of view.
