Experience Astro-tech 1.25" 99% Reflectivity Dielectric Quartz Mirror Diagonal + Free Return [NEWLoF51]

Astro-Tech 1.25" Reflective Diagonal Mirror

The Experience Astro-tech 1.25" 99% Reflectivity Dielectric Quartz Mirror Diagonal + Free Return [NEWLoF51] is a premium accessory designed for telescopes seeking exceptional optical performance. This diagonal stands out with its advanced 99% reflectivity dielectric coatings and a low thermal expansion quartz mirror, offering a significant upgrade over conventional diagonals. With its high transmission and high contrast dielectric mirror coatings, this diagonal ensures that your observations are clearer and more detailed.

Advanced Optical Design

The Astro-Tech AT1DQ diagonal features state-of-the-art 46-layer dielectric mirror coatings that provide a full 99% reflectivity, surpassing the reflectivity of traditional aluminum or silver diagonals. This high reflectivity allows for the observation of extremely faint objects, enhancing your viewing experience. The mirror's finely-polished 1/10th wave quartz substrate, with its smooth surface, reduces light scattering and improves contrast and resolution, making it ideal for critical planetary, lunar, and binary star observations.

Practical Uses and Benefits

The Astro-Tech 1.25" diagonal is compatible with a wide range of telescopes, including Schmidt-Cassegrain, Maksutov-Cassegrain, and refractor models that use a 1.25" star diagonal. This diagonal is not only visually superior but also compact, ensuring that it won't interfere with the scope's drive base. The diagonal's precision-machined aluminum housing, antireflective matte black finish, and soft brass compression ring for eyepieces all contribute to its durability and ease of use. With this diagonal, you can achieve the full potential of your telescope, whether you're a hobbyist or an advanced observer, at a price that's very affordable.
