Overview
The Tele Vue DeLite 7mm is a well-regarded eyepiece for observers who want high magnification without sacrificing comfort or optical clarity. At 7mm, it delivers substantial power on most telescopes, making it a strong choice for planetary work, double stars, and smaller deep-sky objects like globular clusters and planetary nebulae. The 62-degree apparent field of view is wide enough to feel immersive but narrow enough to maintain consistent sharpness across the field.
Where this eyepiece genuinely distinguishes itself is in eye relief. The 20mm of eye relief is generous for a short focal length, meaning eyeglass wearers can use it comfortably without removing their glasses, which is a real advantage many competing 7mm eyepieces do not offer. Tele Vue's fully multi-coated optics minimize light scatter and ghosting, producing contrast that holds up well on bright targets like the Moon and planets.
The sliding eyeguard and Dioptrx compatibility add practical usability during longer sessions. At $305, this is not a budget eyepiece. Observers with lower-cost telescopes may not notice enough improvement over mid-range alternatives to justify the price. But for those with quality optics who want an eyepiece that will last decades, the DeLite 7mm is a serious, reliable choice.

This is a very interesting new line of eyepieces from TeleVue. In retrospect it looks as though these are meant to be replacements for the Radians. TeleVue says they've scailed down the Delos eyepiece design to produce this new series, and they are a home run. The 7mm eyepiece is a truly wonderful p...
Tele Vue sometimes are equiled but rarely beaten in scope occulars, thus I have several of these De Lite eyepieces that are used with a C-5 and a 65mm Pentax ED spotting scope. I also put the correcting lens for my prescription on each one so I do not have to wear glasses. These are comfortable for ...
The definition of eyepiece quality is beyond doupt "Tele Vue",,and the DeLite 7mm proved it to me. Sharp visuals from edge to edge of the field of view, and its weight and size does not enfluence telescope balance by any means. And the adjustable eye relief makes a huge major difference enhancing it...
