William Optics Dura Bright Dielectric Diagonal

This diagonal is designed for telescopes with a 2-inch focuser. If your telescope uses a 1.25-inch focuser, you will need to use a different diagonal, as this one will not fit.

Yes. It includes a 2-inch to 1.25-inch adapter, allowing you to seamlessly switch between larger 2-inch eyepieces and your standard 1.25-inch collection.

Surface precision measures the flatness of the mirror. A 1/10th wave rating is a high standard that minimizes distortion, resulting in sharper, more accurate images of planets and deep-sky objects compared to lower-grade diagonals.

Beyond its sleek aesthetic, the carbon fiber build keeps the diagonal lightweight. This is particularly helpful for maintaining the balance of your telescope setup, as it adds less weight to the rear end than traditional metal diagonals.

Dielectric coatings are highly durable and reflective, ensuring that more light reaches your eye rather than being absorbed or scattered. This results in brighter, higher-contrast views of faint celestial objects.
