Televue 10mm 72° Delos Eyepiece

 

New gadgets are being manufactured every single day with the advancement in technology. With the help of these gadgets, a lot of people can have all the fun they need in order to accommodate their hobbies. One such hobby is star gazing. Everyone wants their star gazing experience to be magical and exciting. Researchers, astronomers and even people who have a passion for star gazing love to accessorize their telescopes every now and then to have more fun with exploring the stars and planets. Mostly the main accessory that everyone wants to be perfect is the eyepiece. Eyepiece designs have a major effect on the viewing ability of the telescope. If you are looking for the perfect eyepiece for your telescope then TeleVue eyepieces should be your choice. 


  • This Tele Vue Delos Eyepiece has a 20.0mm eye relief.
  • Continuously adjustable height eyeguard system that can be locked in any position.
  • This TeleVue 10mm Delos Eyepiece achieves full field sharpness, virtually perfect f θ (theta) distortion mapping, and color neutrality.
  • Realistic 72° apparent field of view. 

 

TeleVue makes premium eyepieces as well as other optics for the astronomers. It has a wide range of eyepiece designs. The very first TeleVue products included 55mm, 26mm, 17mm, 10.4mm, and 7.4mm Plössls; 13mm, 9mm, and 4.8mm Naglers; and a 2.5x Barlow. All of these products are still used proving the worth of the TeleVue products that they never go out of style. But here we are going to feature the notable Televue Delos eyepieces. 

 

The TeleVue Delos eyepieces are much similar to the Ethos eyepiece designs. They share almost all the optical qualities but have a narrower field and longer eye relief than the Ethos. The Delos eyepieces are priced more affordably than the comparable focal length Ethos and a little bit of the field view is compromised, but the good thing is that the performance quality is not at all affected and has the same performance quality as the Ethos. The advantage of getting a Delos eyepiece is that by compromising the field view, more eye relief is gained as well as a lot of your money will be saved for the same quality product as Ethos.

 

One such product is the 10mm Delos eyepiece; this eyepiece is designed in such a way that it works perfectly fine with all kinds of telescopes. You would not even have to worry about the size of the telescope either because the 10mm Delos eyepiece fits with all telescopes no matter what their size is. This model has a variety of cool and amazing features that will clearly impress you once you get your hands on this product. Even if you wear eyeglasses you are not going to have any trouble while using this eyepiece because of its long 20mm eye relief. Most of the products with the same focal length range have a much shorter eye relief making it difficult and troublesome to use for the people who wear eyeglasses. But the 20 mm eye relief of this product and the full 72° apparent field eyepieces provide greater ease to everyone who will use it.

 

The 10mm Delos eyepiece also comes with an eyeguard whose height can be easily adjusted and locked in any desired position by the user. It also contains a soft roll down eyecup made up of rubber which helps to prevent the eye from coming in contact with any ambient light. The eyecup rotates with use and works well if you have TeleVue Dioptrx refractive error correcting lenses to go with it. One of its other notable features is that it helps to improve the image contrast as well. There are some more interesting qualities of these 72° apparent field eyepieces which include high contrast ability, neutral color balance and it even provides a sharp field of view with a good refractive error correction as well as angular magnification error correction. It even has an added feature called the kidney bean effect which is useful for day time viewing.

 

This fantastic product has a barrel of 1.25 inches which is threaded for standard 1.25 inch eyepiece filters. In order to prevent the eyepiece from falling if the thumbscrew is not tight enough while observing, it has a safety groove for the thumbscrew of the focuser. This product has all the precaution measure in place necessary for its longer life as well as user’s safety. This eyepiece can be easily used in a binoviewer because of its narrow barrel. It has rubber grip rings for a strong grip during the winter when the user is wearing gloves. It also comes with covers for both ends of the eyepiece in order to prevent any dirt from getting in. You will not be able to find anything like this product out there in the market that comes along with a promise of a five year warranty and so many amazing features.

 

So, what are you waiting for? Make your planet-exploring experience more exciting and fun with this incredible eyepiece. You will never find the satisfaction you are looking for in any other product. With so many features to play around with, your star gazing experience will be an unforgettable adventure for you.


 

 

 

Product Series

Tele Vue is pleased to introduce the Delos, mid-to-short focal length line of 20mm eye-relief, 72° apparent field of view eyepieces. Every optical, mechanical, and ergonomic aspect was rethought to achieve reference-standard performance for any visual application. 

The Delos was conceived as a narrower field Ethos. Reducing the field to 72° allowed freedom to increase eye-relief, while controlling pupil aberrations, all without making the eyepiece too large. With Ethos performance standards as benchmarks, the Delos design achieves full field sharpness, virtually perfect f θ (theta) distortion mapping, and color neutrality. Image fidelity is maximized utilizing glass matched multicoatings and anti-reflection surfaces throughout the eyepiece.

Contrast is further enhanced with a new, continuously adjustable height eyeguard system that can be locked in any position. Since the Delos eye-lens measures a quite large 35mm in diameter, preventing stray light from reflecting off the first surface and extraneous light from entering your eye pays off in a nice increase in perceived contrast. The eyeguard's sliding action allows for positioning the soft rubber eyeguard at the ideal height to suit the observer's preference. Indicator marks on the eyepiece body are handy reference guides for setting your perfect position. The eye-guard can also rotate for Dioptrx users.

Concept: It was natural to take lessons learned from the tremendously successful Ethos project and apply it going forward. In the fall of 2008, Paul Dellechiaie was tasked to investigate a long eye-relief eyepiece design in the 70° AFOV range, retaining the key performance goals met with Ethos. My father named Paul's design, "Delos." Delos is a beautiful Greek island which happens to be the mythical birthplace of Apollo, god of light. More importantly the name was chosen to give recognition to Paul, principal designer of both Delos and Ethos. — David Nagler
