The Explore Scientific 72° ED 15mm is a premium telescope eyepiece that delivers relaxed mid-power views with a wide, immersive 72° field of view. An eyepiece sets your magnification — this 15mm strikes a great balance for the Moon, planets and open star clusters, giving comfortable power with a generous field that's easy on the eye.

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

Who it's for: Observers who want a comfortable mid-power eyepiece for planets and star clusters with a wide field. Not sure which focal length to pick? Read our guide to choosing the proper telescope eyepiece.

  • 72° apparent field: a wide, immersive view that makes objects feel natural to follow.
  • ED glass optics: extra-low-dispersion elements for sharp, colour-corrected detail.
  • Balanced 15mm: comfortable mid-power for planets, the Moon and open clusters.
  • Waterproof & argon-purged: sealed against fogging and moisture for all-weather use.
  • Comfortable eye relief: designed for relaxed viewing, including for eyeglass wearers.

What magnification will I get?
Divide your telescope's focal length by 15. For example, a 900mm scope gives about 60x with this eyepiece.

What is a 72° apparent field of view?
It's how wide the view appears through the eyepiece; 72° is a generously wide field that makes clusters and star fields especially rewarding.

Why does ED glass matter in an eyepiece?
Extra-low-dispersion glass controls colour and improves sharpness, especially toward the edge of the field.

Does it fit my telescope?
It uses a standard 1.25" barrel, compatible with the vast majority of telescopes and diagonals.
