Baader Planetarium Hyperion 17mm Eyepiece ... $225.95
Most telescopes are supplied with one or two simple eyepieces in the set, which do not exploit the performance of the optics. Moderate contrast and sharpness and small field of vision quickly spoil the fun of the sky observation. With Hyperion eyepieces you get everything out of your telescope!

Tele Vue 18.2 DeLite (EDE-18.2) $349.95
All models have 1¼" barrels and are parfocal with TeleVue's 1¼" Plössl, Panoptic, Nagler, and Delos eyepieces. Named DeLite because that best describes the viewing experience, the name also recognizes designer Paul Dellechiaie's work. The DeLite series is a delightful addition to TeleVue's visionary line of eyepiece developments. Description Just as Delos eyepieces were developed based on TeleVue's Ethos eyepiece design advancements, DeLite is the logical step toward a smaller, more economical and lightweight version of Delos. The 62° apparent field DeLite retains the pure optical quality of Delos along with 20mm eye-relief, unique sliding, locking eyeguard, and is Dioptrx-ready....

Tele Vue 19.0 Panoptic (EPO-19.0) $356.00
Size, weight and performance make the 19mm an ideal mid power chioce. Ideal "soul-mate" to Bino Vue. Parfocal with smaller Plössls and Naglers. Description Using my Wide-Field design as a starting point, I looked to bring Nagler-like performance to the 60+° field class with the Panoptic series. The idea of a lens to "interface" between the eyepiece and Barlow struck me as the proper way to keep size, weight and cost to a minimum while improving edge of field performance even further. I later developed this idea into the Powermates. — Al Nagler Standard on all Panoptics Multi-coatings Blackened lens...

Baader Planetarium MORPHEUS 76° Widefield ... $405.95
The eyepiece is half the optics of a telescope - and when trying to use the optical system to its limits even good middle class eyepieces are becoming the limiting factor.

Tele Vue 16.0 Nagler Type 5 (EN5-16.0) $480.00

Every optical, mechanical, and ergonomic aspect was rethought to achieve reference-standard performance for any visual application. Description 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. With Ethos performance standards as benchmarks, the Delos design achieves full field sharpness, virtually perfect f θ (theta) distortion mapping, and color neutrality. Image fidelity is maximized utilizing glass matched multicoatings and...
