Tele Vue eyepieces are best-in-class, and truly exquisite. The attention to every detail, from producing the highest-quality optics to the fit and finish, and you'll know why you must have at least one in your collection. We bet you can't own just one.
One of the most expensive features of good optics is contrast, and the more, the better. The Tele Vue Ethos is high in contrast, thanks to extra-low reflection high-efficiency coatings tuned to the composition of each element, and flat-finished baffles.
If you compare the 13mm Ethos to other lower-power eyepieces with the same sized field stop (eg: 26mm 50° AF Plossl), the Ethos not only gives you the same field of view and twice the power, but you also get four times the contrast because the skies appear darker.
The Ethos pushes the apparent field of view wide-open; it is incredibly wide at 100°... Stars render as pin-points across the full field. When observing planets like Jupiter, the view is as if you're parked in orbit.
The Ethos design is essentially multiple eyepiece designs blended into one.
