Product Highlights
  • 100° Apparent Field of View
  • 15mm Eye Relief

The Tele Vue 13mm Ethos Ultra Wide Angle Eyepiece is the first astronomical eyepiece with 100° apparent field of view. For a given magnification, it shows 50% more sky than the previous widest-field oculars. While sharpness is inherent to the optical design, contrast is maximized through the intelligent use of flat finished baffles and ultra low reflectance, high efficiency coatings tuned to the composition of each element.

The Ethos is essentially multiple eyepieces, delivering the true field size of a longer focal length, narrower apparent field eyepiece with the benefits of higher power and darker sky background. It can fit both 1.25" and 2" type telescopes.

Accepts DIOPTRIX astigmatism correcting lenses. This allows those with astigmatic vision to enjoy the sharpest viewing experience they've ever had, without using their glasses.
Can be combined with Barlows and Powermates for higher magnifications, without being subject to vignetting.
Will accept 48mm filters by adding the optional EBX-2120 2" extension tube.
Focal Length 13mm
Eye Relief 15mm
Apparent Field of View 100°
Dimensions 2.5 x 5.6" (63 x 142mm) WxH

      Comments about Tele Vue Ethos 13mm Ultra Wide Angle Eyepiece (1.25 & 2"):

      This is my first ultra wide field of view eyepiece, it definitely lives up to its reputation. I've only had it under truly dark skies once so far, but the views were spectacular - wide fields and high magnification. I use a nextar 8" sct and this eyepiece performs well on this scope with and without a f/6.3 focal reducer. The eyepiece is heavy compared to a plossl but from what I hear it's significantly lighter than many naglers.

        I've used this eyepiece in several telescopes from my 4" Schmidt Cassegrain, to a 25" reflector, and in all cases this eyepiece is flawless. Views of the double cluster were breathtaking and nebulae that once looked faint are now "easy" targets. I've tried several other eyepieces and there is simply no comparison (other than the price) Surprisingly it's not as heavy as it looks. This is one eyepiece replaces several, and is my favorite in the Ethos line, I also own a 21mm and 8mm Ethos.

          Comments about Tele Vue Ethos 13mm Ultra Wide Angle Eyepiece (1.25 & 2"):

          The eyepiece was used in a TMB 175 f/8 Apo refractor, great combo. A Pentax ED 65 birding/spotting scope which could not reach infinity focus with it. In the last few weeks, only one night here had steady enough atmosphere to see the Last Quarter Moon in the stark sharpness this eyepiece delivers. Plenty of other nights allowed appreciation of the other virtues: contrast, lack of scatter, accurate color balance, lack of distortion, and finally the unique field of view. The best astro views give a sensation that you are viewing an object and not an image, and this eyepiece delivers. A nice view of Saturn needed a barlow lens for more power. The spotting scope test was mindblowing in a different way. The focus only went from about 8 to about 30 feet, but what a crispy, long-range microscopic world it was with little hairs and spots on twigs. I have new respect for the Pentax objective. I need to use the Ethos for birding on a scope with more focus travel, not tried yet. Got astigmatism? You ought to look into a Televue correcting lens to allow viewing without eyeglasses. Or just enjoy all the other benefits except the extremely immersive field. I would keep the eyepiece warm. The eye relief plus lots of staring may fog it before you're saturated with looking.

          Comments about Tele Vue Ethos 13mm Ultra Wide Angle Eyepiece (1.25 & 2"):

          Though it may be pricey, this eyepiece will replace a half dozen of the eyepieces already in your collection. Its 100-degree apparent field of view takes in as much space as a 22mm, 27mm, or even 30mm wide-angle eyepiece. Stars are tack sharp all the way to the edge: there's no smearing or vignetting anywhere in the field of view. Aim it at a globular cluster like M13 and what looks like a fuzzy ball in other eyepieces suddenly resolves into well-defined swirls of stars. And you've never really seen the Orion Nebula until you've seen it through the Ethos eyepiece. I let a friend use the eyepiece with his Celestron 1100 GPS, and when he pointed it at the Orion Nebula I heard a gasp and he said, "It's like you're floating around in the nebula, right through the stars in the Trapezium!" The eyepiece is pure Tele Vue in quality and fits either 2" or 1.25" focusing tubes. You'll pay a chunk of money for the Ethos but the first time I used it on a dark West Texas night I knew it was worth it.

          Comments about Tele Vue Ethos 13mm Ultra Wide Angle Eyepiece (1.25 & 2"):

          I use this eyepiece for close up deep sky observing with a deep sky filter, the view of M42,M44 & M45, made me feel like jumping right into the eyepiece placing the eye close to the eye lens open up the full 100 degree apparent f,o,v. I have never felt so personally close to space, like looking through a porthole of a spaceship. At 530mm focal lengh Saturn's rings and Titan although small are clear from one edge to the other egde with no distortion. All the reviews that have been placed in the astronony world are not overstating this eyepiece it is a master piece.
