Description

Eyepieces at or near the 10mm range are often considered a mandatory focal length in your collection, as this focal length range is departure point from medium power eyepieces for most telescopes for amateur astronomers. Fainter deep sky objects that do not have the inherent brightness to be observed at higher powers are often perfect for a 10mm. Explore Scientific Waterproof Eyepieces - Comfort, Quality, Value. The Explore Scientific 52° Series„¢ eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality and value versus a comparably priced Plossl.

Another great benefit of these eyepieces is the excellent contrast and ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.

Customer Reviews (4.2 / 5 · 5 reviews)

Nicholas ★★★★★

The 10mm hits that sweet spot between medium and high power, and the 52-degree view makes tracking objects feel effortless. It’s solidly built and the waterproofing is a nice peace of mind for those dewy nights out.

Edward V. ★★★★★

The 52-degree field on this 10mm is noticeably wider than my old stock eyepiece, and the waterproof seal gives me peace of mind for dewy nights. Focus is crisp right to the edge in my scope, and it’s become my go-to for lunar detail.

Riley Y. ★★★★☆

For the price, the 10mm focal length gives me a solid medium-power view that works well on both my scopes. The eye relief is comfortable enough for my glasses, though I did have to adjust the eyecup slightly.
