Overview
The Explore Scientific 82-degree 6.7mm eyepiece is a strong choice for observers who want a genuine wide-field, high-magnification experience without stepping into premium price territory. At 6.7mm focal length, this eyepiece delivers serious magnification on most mid-range telescopes, making it well suited for planetary work, tight double stars, and globular clusters where you want both power and a spacious field of view. The 82-degree apparent field of view is the headline feature here.
Compared to standard 50 to 68-degree eyepieces at similar focal lengths, the difference in immersion is noticeable, particularly during planetary sessions when you want room to track without constantly nudging your mount. The EMD multi-layer coatings do a solid job managing contrast and light transmission, which matters when you are trying to pull out subtle surface detail on Jupiter or Saturn. Weighing in at 240 grams, it adds some heft to a focuser, so owners of smaller refractors or lightweight Dobsonians should check their balance.
At $139.99, it sits in a competitive but honest price range. The 4.8 out of 5 rating across its reviews reflects consistent satisfaction, though the relatively small review count means you should weigh that accordingly.

To start with, the true field of view of this 6.7mm is one minute of arc larger than the 10mm Plossl that l own and field transit time at 0 degrees declination 5 seconds longer, plus --- I GET NEARLY 50% MORE MAGNIFICATION THAN THE 10MM!!!! The side by side comparison of these 2 eyepieces is truly a...
Great product
Good build quality for the price. This is my go to piece. Gives about 180x out of my xt8 which is nearing its limit once you go to the deep space objects. Excelent for planetary viewing.
