Baader Planetarium MaxBright Mirror Diagonal

Standard thumbscrews often mar the barrel of your eyepiece and can cause slight alignment shifts. The Clicklock mechanism uses a three-point clamping system that applies even pressure around the entire barrel, ensuring your eyepiece is perfectly centered and securely held without leaving any scratches.

This diagonal is designed for telescopes with a 2-inch focuser drawtube. As long as your telescope accepts standard 2-inch accessories, it will fit securely.

Dielectric coatings are significantly more durable and resistant to oxidation than standard aluminum coatings. They provide 99% reflectivity, which ensures that virtually all the light gathered by your telescope reaches your eye, resulting in brighter, higher-contrast views.

Yes, surface accuracy determines how well the mirror preserves the wavefront of the light coming from your telescope. A 1/10 wave rating ensures the mirror itself introduces no optical aberrations, allowing you to see the sharpest possible images your telescope is capable of producing.

The hard-coated dielectric surface is much more robust than traditional coatings. While you should always be gentle, it is significantly more resistant to cleaning-related micro-scratches, making it easier to maintain over the long term.
