As great as I had hoped...

Performs exactly as I had hoped. Super sharp clarity and, as a glasses-wearer, the eye relief is WONDERFUL!

Great contrast and clean edges

I use this is my 10in F/5 Newtonian. Stars look like their sitting on black velvet and are round out to the edge of the FOV. The slide up eyecup makes setting the eye placement easy every time. Would recommend.

Love my Tele Vue 10mm Ethos

Great Tele Vue Ethos eyepiece. I use it when the seeing in my particular area is above average. 100 degree view is just incredible!

Televue Delos 4.5 mm eyepiece

Fantastic eyepiece. The views of Jupiter are incredible. Cassini division in Saturn rings is easily visible. I recommend this eyepiece for planetary observation

Excellent eyepiece for visual astronomy

I purchased the 17.3 Delos for a new telescope (f5 12.5" Newtonian reflector) because I have been using one for several years at my astronomy club's observatory, and found it to be an excellent telescope on a fast (f3.5 16", plus Paracorr) Newtonian. Sharp stars to the edge, nice balance of field flatness and distortion (very low in both cases). Great eye relief.

Great eyepiece!

I absolutely love this Delos Eyepiece. It is very crisp sharp I am very impressed with televue optics only complaint wish they were cheaper. The eye relief is great and the images are great the eyepiece adjusts easy for your eyes compared to the explore scientific 82 series I can say the contrast maybe a little more on the es but the Delos is more crystal clear tack sharp and just a joy to look though.

Perfect, like all TV equipment.

Not much to say here - these the best EPs money can buy.

Tele Vue Delos 17.3mm

This is the best eyepiece I've used with my 4 inch refactor. The images are clear and sharp across the field. It is now my favorite eyepiece and I will defiantly add another Delos to my collection!

Nice eyepiece!

I purchased this eyepiece at the suggestion of the rep at Televue. After quick delivery and waiting out two rainstorms I was upset that I spent the money for this piece. I read the instructions and read where this line of EP's adjust for Astigmatism. I tried it on the next clear night and was amazed! I saw Saturn with the utmost clarity after I made the adjustment. I saw the gap in the rings and bands around the planet. This one is a keeper and may be accompanied by the rest of the set!

This is the best eyepiece I've used with my 4 inch refactor. The images are clear and sharp across the field. It is now my favorite eyepiece and I will defiantly add another Delos to my collection!

Because of its superior design and advanced features, the 10mm Ethos-SX 2"/1.25" Eyepiece offers an unparalleled viewing experience. With a 100-degree apparent field, it delivers a viewing area that is 50% larger than the 82-degree Naglers, providing a more expansive and immersive observation experience.

This eyepiece is designed with comfortable eye-relief and accepts DIOPTRX eyesight astigmatism correctors, making it a versatile choice for users with varying vision needs. Its high contrast and on-axis sharpness make it an excellent choice for planetary viewing, offering crisp, clear images of celestial bodies.

The 10mm Ethos-SX Eyepiece is a "do-it-all" accessory, compatible with all scopes that can accommodate this focal length. It effectively "fills the hole" between the 13mm and 8mm eyepieces, making it the perfect centerpiece for a 17mm/10mm/6mm Ethos set.

One of the key benefits of this eyepiece is the combination of a large apparent field of view and shorter focal length. This combination allows for higher magnification, resulting in a darker sky background. This enhances the visibility of fainter stars and reveals more detail on all deep sky objects.

The Ethos-SX Eyepiece offers a significant magnification and contrast boost, providing dramatic views that were previously unattainable with any telescope. The smaller exit pupil also reduces eyesight limitations, making it a more accessible option for many users.

In addition to matching all the key performance criteria of its 13mm sibling, the 10mm Ethos-SX Eyepiece is lighter in weight and smaller in diameter, making it more suitable for use with a binocular viewer. This makes it a practical and high-performing addition to any astronomy enthusiast's toolkit.
