The Orion 1.25-Inch Dielectric Mirror Diagonal offers exceptional performance with its advanced dielectric coating, which achieves an impressive 99% reflectivity. The major disadvantage of mirror diagonals is that unless the reflective coating is properly applied they can scatter light rendering lower image contrast. The good thing is the Orion dielectric mirror diagonal largely solves this problem, providing you with crisp and high contrast imaging when observing your favourite sky objects. With such a high reflectivity (99%), your views of the starry skies are bright, detailed and full of contrast. 

This high reflectivity ensures bright, detailed, and high-contrast views, making it an excellent choice for users seeking superior image quality.

Features:

• Dielectric Coating: Provides 99% reflectivity for high image contrast and brightness, significantly reducing light scatter and improving overall viewing experience.
• Durable Construction: The mirror’s dielectric coating is highly durable, ensuring long-lasting performance without degradation over time.
• Optical Quality: Diffraction limited for crisp and clear images.
• Viewing Angle: 90-degree viewing orientation enhances comfort during extended observation sessions with refractor, Maksutov-Cassegrain, or Schmidt-Cassegrain telescopes.
• Clamping Mechanism: Equipped with a twist-tight clamping system that securely grips 1.25" eyepieces and accessories. This mechanism prevents scratches and eliminates the need for thumbscrews, making it easy to adjust even with gloves.
• Filter Threads: The 1.25" nosepiece barrel is threaded to accept 1.25" filters, allowing for quick and convenient filter changes.
• Construction: Features a machined and anodized aluminum housing with internal glare baffles to reduce internal reflections and glare.

The Orion 1.25-Inch Dielectric Mirror Diagonal is designed for users who demand high performance and reliability in their astronomical observations. It is compatible with most telescopes, but not recommended for use with Newtonian reflectors. Protective caps are included to keep the diagonal clean when not in use.
