The fit, finish and performance of Celestron's 4-element premium Plossl eyepiece is remarkable in a market that is awash with similar but inferior products.

Features include blackened lens edges to minimize internal reflection and maximize contrast, fully multi-coated optics for maximum light transmission and a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces.

Best suited for telescopes with f-ratios f6 or slower.

All focal lengths offer 50º field-of-view except the 40mm which offers 42º

Threaded barrel accepts 1.25" filters and features a 'safety undercut' to prevent the eyepiece falling out of the focuser.

32 and 40mm: due to the 1.25" barrel size the 32 and 40mm eyepieces actually show the same area of sky so, for visual use, the 32mm is the better choice. The 40mm is however useful when a compact camera is positioned over the eyepiece for afocal photography. 

Note to spectacle wearers: Plossl eyepieces with 15mm and longer focal lengths are good choices for spectacle wearers but for shorter focal lengths the Celestron XCel or William Optics SPL series eyepieces have greater eye-relief so are better suited.
