The Celestron 1.25" Mirror Diagonal Twist-L is a high-quality telescope accessory designed specifically for astrophotography and astronomical observations. This dielectric star diagonal allows for precise light path deflection at a 90-degree angle, ensuring comfortable and ergonomic viewing. The dielectric mirror is coated with 58 special layers, providing an impressive reflectivity of over 99 percent. This ensures maximum light transmission to the eyepiece, resulting in brighter and sharper images. The innovative Twist-Lock mechanism securely holds eyepieces in place and prevents damage to the eyepiece housings, while an integrated housing stop offers additional protection. The design features machined, black anodized aluminum with orange anodized rings, which not only provides an appealing look but also minimizes stray light and glare. This diagonal is therefore an ideal choice for astronomy enthusiasts who value optical quality and user-friendliness.
