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!

From the renowned brand Tele Vue, the 10mm Delos Eyepiece is an innovative and high-quality tool for astronomical observation, offering a 20mm eye relief and a wide 72-degree apparent field of view. This eyepiece was meticulously designed as a more compact alternative to the Ethos range, without compromising on performance or image quality.

The reduced field of view to 72 degrees provides the freedom to enhance eye-relief and effectively control pupil aberrations, all while maintaining a manageable size for the eyepiece. Drawing from the high standards set by the Ethos range, the Delos eyepiece delivers sharp, full-field clarity, virtually flawless theta distortion mapping, and color neutrality.

The Delos eyepiece optimizes image fidelity by utilizing glass-matched multi-coatings and anti-reflection surfaces throughout the eyepiece. This, coupled with a new continuously adjustable height eyeguard system that can be locked in any position, significantly enhances contrast.

The Delos eyepiece features a large 35mm eye-lens diameter, which effectively prevents stray light reflection off the first surface and blocks extraneous light from entering your eye. This results in a noticeable increase in perceived contrast, enhancing your viewing experience.

The eyeguard's sliding action allows for the soft rubber eyeguard to be positioned at the ideal height to suit the observer's preference. Indicator marks on the eyepiece body serve as handy reference guides for setting your perfect position. Additionally, the eye-guard can rotate, making it a versatile choice for Dioptrix users.

Whether you're observing stars, planets, or deep sky objects, the 10mm Delos Eyepiece from Tele Vue is a durable and user-friendly choice that delivers exceptional performance and viewing comfort.
