Celestron Dielectric Star Diagonal with Twist Lock

Upgrade your current star diagonal to the Celestron Dielectric Star Diagonal, 2” with Twist-Lock to ensure maximum light transmission and superior optical quality. This premium star diagonal provides a 90° viewing angle, making it perfect for comfortable use with refractor and Cassegrain-type telescopes.

Featuring 58 layers of dielectric coatings, this star diagonal offers an over 99% reflective surface, allowing the maximum amount of light collected by the telescope to reach the eyepiece. This results in brighter, sharper images without the need to invest in a new telescope. Additionally, the twist-lock eyepiece holder ensures that eyepieces remain centered in the diagonal, providing optimal opto-mechanical alignment between the telescope and eyepiece.

The 2” star diagonal also allows for the use of larger 2” eyepieces, providing a wider field of view, or standard 1.25” eyepieces with the included stepdown adapter. Unlike traditional thumb screws, the twist-lock mechanism prevents scratching or engraving on the eyepieces. Furthermore, the integrated 2” barrel stop prevents long-barreled 2” accessories from damaging the mirror.

Crafted with machined black anodized aluminum, the Celestron Dielectric Star Diagonal, 2” with Twist-Lock boasts high-end finishes, including orange anodized twist lock rings for enhanced visibility. The interior of the Schmidt-Cassegrain adapter and 2” barrel are glare threaded and painted flat black to prevent glare.

For added flexibility, this diagonal includes two interchangeable barrels to connect to a variety of telescopes without the need for additional adapters. Whether your telescope accepts 2” barrels in the focuser or uses a threaded connection, the included barrels provide a secure connection to the diagonal.

With its top performance in both reflectivity and optical quality categories, this premium star diagonal delivers superior views through your telescope without affecting optical performance. Don’t settle for lower quality diagonals that can dim your view and degrade optical quality. Upgrade to the Celestron Dielectric Star Diagonal, 2” with Twist-Lock and enjoy better views through your telescope with its diffraction-limited optics and dielectric coatings.
