Overview
The Explore Scientific 82° 14mm sits in a sweet spot that many amateur astronomers find themselves reaching for night after night. At 14mm with an 82-degree apparent field of view, it delivers a genuinely wide, immersive view without sacrificing too much magnification. On a typical f/6 refractor or reflector, you are looking at magnifications in the 50x to 80x range, useful for open clusters, large nebulae like the Orion Nebula, and even planetary work when seeing is average. The field is wide enough to fit most Messier objects comfortably and make star-hopping noticeably easier.
The EMD coatings do their job well, producing good contrast and light transmission that shows up clearly on faint nebulosity and galaxy structure. The edge-blackened lens elements help control scattered light, which benefits planetary and bright star views. Eye relief is comfortable for most observers, though eyeglass wearers should confirm it suits their needs before purchasing. The waterproof, nitrogen-purged housing is a practical feature for observers in humid climates or those who leave gear outside as temperatures drop.
Weighing only 280 grams, it adds minimal load to a focuser. At $149.99, it represents solid value for a wide-field eyepiece at this quality level.
Key Features
- 14mm focal length offers versatile mid-range magnification suited to both deep sky objects and planets under steady seeing
- 82-degree apparent field of view creates an immersive, wide view that simplifies star-hopping and object framing
- EMD fully multi-coated optics improve light transmission and contrast, which benefits faint nebulosity and galaxy detail
- Edge-blackened, low-dispersion glass elements reduce internal scatter for cleaner, higher-contrast views
- Nitrogen-purged, O-ring sealed housing prevents internal fogging and dust accumulation in humid or cold conditions
- Lightweight at 280 grams, adding minimal strain to sensitive focusers on smaller mounts
- Strong 4.7-star rating across 55 Amazon reviews suggests consistent optical and build quality across units

Bought this eyepiece in 14mm, to complement the 10mm and 20mm Celestron Kellner eyepieces that came with my first telescope, a 102mm Celestron refractor. The quality of this eye piece is far above the eyepieces that came with my scope, so much so it feels like an entirely new instrument! The field o...
Views are broad and very sharp, I will be buying more Explore Scientific eyepieces.
I like this eyepiece because it is a high-quality lens, it gives very clear images and has a great field of view. It’s also powerful enough for many deep sky objects, but not too powerful.
