TeleVue Everbrite 1.25" 90° star diagonal (16903)

TeleVue Everbrite 1.25" 90° Star Diagonal (Model 16903)

The TeleVue Everbrite 90° star diagonal is designed to deliver brighter, more natural images through advanced dielectric mirror technology. Its exclusive Everbrite coating reflects 99% of light across the entire visible spectrum, producing exceptionally bright and color-neutral views. The mirror is applied to a Pyrex substrate with a surface accuracy of 1/10 wave flatness, ensuring high optical precision and minimal image degradation.

Each mirror is carefully inspected under conditions far more demanding than those encountered during normal telescope use. This rigorous testing guarantees that the diagonal allows your telescope to perform at its full optical potential. The result is enhanced contrast, improved brightness, and highly accurate color reproduction.

The diagonal body is precision-machined from a solid block of aluminum to ensure permanent alignment and long-term durability. The one-piece construction prevents the body from loosening or unscrewing under the weight of heavy accessories, a problem sometimes encountered with other designs. A brass compression ring securely holds the eyepiece without marring its barrel, while internal anti-reflection threading reduces stray light.
