This durable and sturdy star diagonal is designed to maximize light transmission without compromising optical quality, enhancing your viewing experience with brighter, sharper images. This premium star diagonal is an ideal upgrade for your existing telescope setup, reflecting the telescope's light path at a comfortable 90½ angle.

The diagonal's mechanical parts are crafted from machined black anodized aluminum, with the exception of the twist-lock rings, which are orange anodized for easy visibility.

The interior of the barrel is threaded and painted flat black to prevent glare, ensuring a seamless and uninterrupted viewing experience.
