The 90° Dielectric Star Diagonal from Celestron has a 1.25" nosepiece and holder to make it compatible with the most popular size of gear from eyepieces to Barlows, filters, and a near-infinite array of accessories. Designed with diffraction-limiting optics, its BK7 mirror is treated with 58 layers of dielectric coatings that produce a reflective surface greater than 99% so more incoming light makes it to your eye—this is especially important when viewing dim deep-sky objects where every photon of light is important.

For the eyepiece holder side of the diagonal, Celestron eschews convention and replaces the ubiquitous three thumbscrews to tighten the interior compression ring with a twist-lock. Utilizing a twist-lock not only makes swapping your eyepieces and accessories faster and easier, it properly centers the eyepiece and maintains proper optical alignment. The nosepiece is outfitted with standard filter threads so you can install your favorite filter—like a moon, nebula, or light pollution—without having to move it from one eyepiece to another as you go about your observation sessions. The aluminum housing has a black anodized finish, and the interior is painted flat black with blackened threads to reduce reflections.
