The Explore Scientific 92° ED 25mm is a premium ultra-wide telescope eyepiece that delivers panoramic, low-power views with a breathtaking 92° apparent field of view. An eyepiece sets your magnification — this longer 25mm keeps power low so faint deep-sky objects stay bright — while the huge 92° field and 2" barrel frame sprawling star clusters, big nebulae and Milky Way starfields in one immersive, wraparound sweep.

Extra-low-dispersion (ED) glass keeps colours tightly focused for sharp, high-contrast detail, and this 2" eyepiece is fully multi-coated and argon-purged so it won't fog internally in cold or damp conditions.

Who it's for: Deep-sky observers who want the most panoramic low-power views for clusters, nebulae and starfields. Not sure which focal length to pick? Read our guide to choosing the proper telescope eyepiece.

  • 92° apparent field: an ultra-wide, immersive "spacewalk" view.
  • ED glass optics: extra-low-dispersion elements for sharp, colour-corrected detail.
  • Panoramic 25mm: low power that keeps faint objects bright for the widest deep-sky sweeps.
  • 2" barrel, fully multi-coated: premium build with high light transmission.
  • Argon-purged & sealed: resists fogging and moisture for all-weather use, with long eye relief.

What magnification will I get?
Divide your telescope's focal length by 25. For example, a 1200mm scope gives about 48x with this eyepiece.

Why choose the 25mm in this series?
It gives the widest, lowest-power panoramic view in the 92° line — ideal for big clusters, large nebulae and rich starfields.

How immersive is a 92° field?
Very — it fills your vision so you feel surrounded by the view rather than looking through a porthole.

Does it fit my telescope?
It requires a 2" focuser or diagonal.
