This high-quality mirror diagonal features sophisticated, lab-tested dielectric coatings that boast an astounding 99% reflectivity. With such high reflectivity, your views of starry skies will be bright, detailed, and full of contrast. Dielectric mirror coatings are more durable than enhanced aluminum coatings, so you'll enjoy years of exceptional performance without degradation.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe machined and anodized aluminum diagonal housing features machine-threaded internal baffles to ensure high-contrast performance and eliminate pesky internal reflections and glare. A non-marring compression ring collar is built-in to the 1.25\" adapter to safely secure any inserted 1.25\" telescope eyepiece without scratches. Protective caps are included to keep the diagonal free of dust when not in use.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThis diagonal requires approximately 9cm inward focus travel relative to an eyepiece's focus position without the diagonal.
