The Explore Scientific 92 degree ED 20mm eyepiece with a 2 inch barrel is designed for immersive, wide field viewing with a balance of brightness and magnification. It is particularly effective for observing deep sky objects while maintaining an expansive perspective. The ultra wide 92 degree apparent field of view creates a panoramic experience that enhances the sense of depth and scale. Objects remain in view longer, making observation more fluid and engaging.

The extra low dispersion glass ensures that image quality remains sharp and well corrected. Color fringing is minimized, and contrast is enhanced, resulting in a clean and detailed image. The eyepiece is built for comfort, with long eye relief that supports extended observation.

This focal length is ideal for those who want a wide field experience while still maintaining enough magnification to reveal structure and detail.

Chloe ★★★★★

I was blown away by how crisp the stars looked through this 20mm eyepiece—the 92-degree field really does pull you into the view. The 2-inch barrel feels solid and the image stays bright even at the edges.

Richard ★★★★★

The field of view on this 20mm eyepiece is genuinely immersive, and even with my moderate telescope, stars stay sharp right to the edge. The two-inch barrel feels solid when locking into the focuser, and the 92-degree apparent field makes sweeping the Milky Way a real treat.

Kevin G. ★★★★★

I’ve been using this 20mm eyepiece for a few nights now, and the 92-degree field of view is honestly breathtaking — it feels like I’m floating through space. The 2-inch barrel makes swapping it in and out of my scope quick and easy.
