TeleVue Everbrite 2" 90° mirror star diagonal (56978)

TeleVue Everbrite 2" 90° Mirror Star Diagonal (Model 56978)

The TeleVue Everbrite 2" 90° star diagonal is engineered 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, color-neutral views. The mirror is applied to a Pyrex substrate with a surface accuracy of 1/10 wave flatness, ensuring outstanding optical precision and minimal image degradation.

Each mirror is individually inspected under demanding optical conditions that exceed normal telescope use. This rigorous quality control guarantees that the diagonal allows your telescope to perform at its maximum potential. The result is enhanced brightness, improved contrast, and faithful 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 loosening or unscrewing under the weight of heavy accessories. A brass compression ring securely holds eyepieces without damaging their barrels, and internal anti-reflection threading minimizes stray light.
