View All Eyepieces

Takahashi's TOE eyepieces are the ultimate in high magnification visual observation. These eyepieces, coupled with a premium telescope, will delivery performance close to the diffraction limit over the entire field of view.

The Explore Scientific 100° series are hyper-wide-angle (for want of a better word) eyepieces that offer a fully immersive viewing experience. You might even forget there is an eyepiece between you and the universe!

Introducing Meade’s Series 5000 Premium Wide-Angle (PWA) Eyepieces. These high-quality eyepieces feature a fully multi-coated optical design with premium-grade, exotic optical glass for the best possible image correction in color, contrast, and brightness.

Tele Vue's philosophy of "showing no field unless it's fine" stresses full field image quality as the ingredient for impressive views. Blackened lens edges, anti-reflection threads and rubber eyeguards deliver maximum contrast.

Thanks to their long focal length design, the new XW30-R and XW40-R eyepieces will let you observe large celestial bodies spreading across the night sky

The Delos was conceived as a narrower field Ethos. Reducing the field to 72° allowed freedom to increase eye-relief, while controlling pupil aberrations, all without making the eyepiece too large.

High-performance eyepiece for astronomical telescopes that offers exceptional versatility and image quality. Stunning build and high quality SMC coatings.

This Sky & Telescope "Hot Product" is designed to produce the largest true field possible in a 1¼" eyepiece. (Its 27mm field stop is the same as the 32mm Tele Vue Plössl).

The Hyperion design has has both a 31.7mm (1 1/4") and 50.8mm (2") barrel for fitting into either size focuser or diagonal. Both barrel sizes have a safety groove for safe use in your telescope. Complete with 4 Hyperions plus the hard case to eventually house them all.

The concept for this eyepiece series was proposed by Tele Vue President David Nagler, with performance parameters giving it the fundamental characteristics (the ethos) of a Tele Vue eyepiece: high contrast, comfortable eye relief and full field sharpness.

The Explore Scientific 92° Argon 12mm LER Eyepiece is the most powerful of the Explore Scientific LER range. These eyepieces are designed to balance the modern demands of field sharpness over a wide apparent field, with long eye relief, which is of particular benefit to those who wear glasses while observing.

The Explore Scientific 92° Argon 17mm LER Eyepiece is the first in the line of Explore Scientific's 92° range of Argon-purged eyepieces. These eyepieces are designed to balance the modern demands of field sharpness over a wide apparent field, with long eye relief, which is of particular benefit to those who wear glasses while observing.
