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.
