Celestron Luminos 15mm 1.25in 82° Eyepiece

15mm 82° Eyepiece

The Celestron Luminos 15mm eyepiece delivers an expansive 82-degree apparent field of view through a standard 1.25-inch barrel. It is built for astronomers who want immersive, wide-angle views of stars, planets, and deep-sky objects without moving to a larger barrel format. The six-to-seven element optical design is fully multi-coated for high light transmission and contrast.

Wide field with parfocal convenience

The 82-degree field provides generous eye relief and a spacious viewing window that works well across a range of telescope focal ratios. Parfocal design across the Luminos line means you can swap this 15mm unit for other focal lengths in the series with minimal refocusing, preserving momentum during an observing session. Optical performance holds up at high powers but exits the lineup at the shortest focal lengths.

Anodized aluminum body with twist-up eyecup

A polished, anodized aluminum housing resists wear and corrosion while a rubberised equatorial grip ensures secure handling in cold or damp conditions. The retractable eyecup twists up via the rubber grip to accommodate both eyeglass wearers and uncorrected vision. Standard 1.25-inch threading accepts common filters, so the eyepiece slots into existing accessory kits without adapters.
