Series 5000 2 inch Enhanced Dielectric Telescope Diagonal

This diagonal is designed for 2-inch focusers and includes adapters for both 1.25-inch eyepieces and Schmidt-Cassegrain (SCT) telescopes. It is fully compatible with most standard refractor and catadioptric systems.

The dielectric coating provides 99% reflectivity across the visual spectrum, which is significantly higher than standard aluminum coatings. This results in a noticeably brighter, higher-contrast image, especially when observing faint deep-sky objects.

Yes, the non-marring compression ring uses a brass band to secure your eyepiece rather than a metal thumbscrew pressing directly against the barrel. This prevents unsightly scratches and gouges on your equipment while ensuring a firm, centered fit.

Pyrex is a thermally stable glass, meaning it is less prone to expanding or contracting as temperatures fluctuate during a long night of observation. This stability helps maintain precise optical alignment and image sharpness throughout your session.

The housing is constructed from black anodized aluminum, which is both lightweight and rugged. It is built to withstand the rigors of frequent setup and teardown without compromising the internal optical alignment.
