Tele Vue Delos 10mm Eyepiece (1.25")
Key Features
  • 10mm Focal Length
  • 72° Apparent Field of View
  • 1.25" Diameter Barrel
  • Anti-Reflective Multi-Coated Optics
Taking design inspiration from the venerable Ethos line but with a narrower field of view to provide users with a long more comfortable eye relief, the Tele Vue Delos 10mm Eyepiece was designed for easy long-duration lunar and planetary observation. Index-matched anti-reflective multi-coatings applied to the glass lenses were engineered specifically to maximize light transmission, which produces sharp, bright, high-contrast, and color-faithful images across the entire spacious 72° apparent field of view. Its adjustable-height rubber eyecup helps to further enhance contrast by preventing stray light from entering the user's peripheral vision, which can interfere with the image seen through the ocular. The eyepiece is offered with a 1.25" diameter barrel for compatibility with a wide variety of filters and accessories, and is parfocal with Tele Vue Group B eyepieces so no refocusing is required when switching between eyepieces within the group.

Fantastic Eyepiece

I have a Celestron Regal 100 ED spotting scope - it's one of the few spotting scopes that will accept industry standard telescope eyepieces. The fixed focal length eyepieces are far superior to the zoom eyepieces that come with most spotting scopes. I wanted a 10mm eyepiece for it but I didn't want to spend the money on the Televue Delos... so I decide to try a Pentax SMC XW but the Pentax ended going back to BH Photo. My scope is used for both terrestrial & celestial viewing. It has a 540mm focal length (f5.4) and maybe that plays a role but the Pentax was causing too much eye strain - it was just too difficult to get your eye in exactly the right spot (the Pentax was very unforgiving in that respect). Both eyepieces were 10mm, both have a 20mm eye relief, and both have excellent glass... so they should make for a good comparison. Also, let me add that I didn't have them side-by-side to compare under the same conditions. But here's my take... both eyepieces produced very clear images. The Delos seemed to have slightly better contrast and a slightly brighter image. But most important to me was that the Delos is a pleasure to use - I could have spent all day behind the Delos eyepiece. No regrets with the Televue Delos. In fact I will probably be getting more and ebaying my other/lesser eyepieces.

TeleVue always has the best. The Delos has some of the best features of all their models. This eyepiece joins another to be used in a binocular that accepts 1.25 eyepieces. I like the barrell adjustments and the easy view. Excellent eyepiece.

The 72 degree apparent field of view is great. I have a 14 mm Delos as well, and the 10 mm lens is a great step up in magnification, with out losing to much clarity.

If you are looking for the best then you found it. Only thing that comes close or is an equal for some people is the Pentax. I feel like i am looking into another world compared to the cheaper EP's In my 8 LX90 it gives me 1mm exit pupil which is perfect for me and the adjustable height eye guard is one of the best i have seen. Truly a beautiful Eyepiece for planetary Viewing.

This eyepiece has provided crystal clear magnification. The 20mm eye relief is great for eyeglass wearers like me. Televue quality at a price that is less than the Ethos or Nagler eyepieces. I will be purchasing another Delos soon.
