Explore Scientific 92° 17mm 2" Waterproof Eyepiece

Introducing this Explore Ultra-Wide Eyepieces that delivers Comfort, Quality, and Value. The eyepieces are hyper-wide class oculars that can transform your visual astronomy experience. You may be startled at the vast expanse of inky black sky you catch, bringing your eye for the first time to a 92° Series eyepiece, and after a while, you may forget you have an eyepiece. Between you and the universe! Objects are easier to locate with an apparent field of view close to the maximum for hyper-wide eyepiece design. Still, for non-driven telescopes, the thing will continue in the field of view for an extended period before any adjustments are made.

One 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 beneficial when observing faint objects because using averted vision puts the image on the part of your eye that is more sensitive to light, allowing you to see softer photos.
