Great eyepiece for this beginner. I?ll save my nickels and dimes and order the 10mm Delos then I?ll be set.

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

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.

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

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

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.

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.

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

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!

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!

Bring the cosmos closer with the Tele Vue 17.3mm Delos Eyepiece, expertly engineered for high-contrast solar system and deep space observation. This versatile eyepiece is compatible with all telescope types and sizes, making it an essential tool for both amateur stargazers and seasoned astronomers.
Designed with a generous 20mm eye relief, this eyepiece is perfect for eyeglass wearers, ensuring comfortable viewing sessions without compromising on image quality. The Tele Vue 17.3mm Delos Eyepiece is also compatible with Tele Vue Dioptrx astigmatism-correcting lenses, offering the option to observe the night sky without the need for glasses.
The adjustable height eyeguard, complete with a soft rolldown eyecup, shields the eye from ambient light, enhancing image contrast for a more immersive viewing experience. The eyeguard height can be securely locked at any desired point, providing a customized fit for every user.
Experience the high contrast, neutral color balance, and full field sharpness that the 17.3mm Delos Eyepiece offers. It effectively controls astigmatism, field curvature, lateral color, and angular magnification distortion, delivering clear and sharp images of celestial bodies.
The Delos Eyepiece also boasts low pupil sensitivity, minimizing the 'kidney bean effect' often experienced during daytime use. The 1.25" barrel, threaded for standard 1.25" eyepiece filters, features a safety groove machined into the chrome barrel to engage your focuser thumbscrew, preventing the eyepiece from falling during observation.
The main eyepiece barrel is designed to be narrow enough to comfortably use a pair of 17.3mm Delos in a binoviewer. Rubber grip rings ensure a secure grip, even in cold weather or when wearing gloves. Dust covers are included for both ends of the eyepiece, keeping your equipment clean and ready for your next stargazing adventure.
