Description

Explore Ultra-Wide Eyepieces - Comfort, Quality, Value. The Explore Scientific 100° Series eyepieces are hyper-wide class oculars that can transform your visual astronomy experience. You may be startled at the amazingly wide expanse of inky black sky you behold the first time you bring your eye to a 100° Series eyepiece, and after awhile, you may even forget that you have an eyepiece between you and the universe! With an apparent field of view that is close to the maximum for hyper-wide eyepiece design, objects are not only easier to locate, but for non-driven telescopes the object will stay in the field of view for a very long time before any adjustments need to be made.

Another great benefit of hyper-wide eyepieces is the 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.

Olivia ★★★★★

I was blown away by how sharp and contrasty the view is through this 25mm eyepiece—the 100° field makes scanning the Milky Way feel like floating through space. The AR coatings really cut down glare on Jupiter, and the eye relief is comfortable enough for my glasses.

Sofia U. ★★★★★

The 2" barrel fits solidly in my focuser, and the argon purging gives me peace of mind during dewy nights. Sharp stars right to the edge make deep-sky observing a real treat.

Chloe R. ★★★★★

The wide field is incredible—saturn's rings practically filled the view with my 12" dob. Even with my glasses on, the 20mm eye relief gives me the whole picture without any blackouts.
