Lunt 1.25" 90 Degree Star Diagonal

Erect Image Diagonal

The Erect Image Diagonal provides a correct image orientation for both Refractor and Cassegrain telescopes, offering a view that is left-right and up-down correct. In contrast, a standard 90° diagonal delivers only an up-down correct image while reversing the left-right orientation. The 45° design of this diagonal also ensures a comfortable viewing angle, making it ideal for terrestrial observation such as bird watching or building viewing.

Featuring a high-quality, full-size Amici prism, this diagonal ensures a fully illuminated field of view and effectively prevents vignetting. The resulting images are sharp, clear, and crisp, offering excellent visual performance.
