A Triple-Digit Field of View
Tele Vue's new 13-mm eyepiece is about to transform deep-sky observing.
S&T RATINGS
Optical Performance
Sensibly perfect. No meaningful improvements possible.
Just as the original 13-mm Nagler set a new standard for deep-sky observing in 1981, the Ethos sets a new standard today. Owning one will guarantee long lines at your telescope during any star party.
[I]f I were dropped on a desert island tomorrow with the 12-inch scope and only one eyepiece, I?d want it to be the Ethos.
Some of the views were simply stunning. The globular cluster Messier 13 in Hercules appeared as a sprawling sphere with thousands of resolved stars, many sweeping outward in sinuous arcs.
Even under the most critical examination, bright stars look sharp and round across the entire field.
The Ethos hasn?t sacrificed one bit of on-axis performance in achieving its 100° apparent field.
[T]he view of a starry sky with the Ethos and TV-NP127is is nothing short of breathtaking. Besting the fields of other astronomical eyepieces by more than 20% in diameter and more than 50% in area, Ethos is a stunning optical achievement.
