T-2 Maxbright 1.25" Mirror Diagonal

The Baader T-2 Maxbright 1.25" Mirror Diagonal is a precision-engineered optical component featuring proprietary Maxbright all-dielectric mirror coatings that deliver 99% reflectivity with minimal light scatter. Constructed from Sitall ceramic glass with a zero expansion coefficient, it maintains 1/10 wave flatness across the 35mm mirror surface, making it ideal for high-contrast planetary and lunar observation at high magnification. The modular T-2 system design allows complete configurability with Baader accessories for use in both 1.25" and 2" focusers, and integrates seamlessly with digital imaging applications and binoviewers. With durable coatings that resist scratching and a precision-machined aluminum housing supporting perfect 45-degree alignment, this diagonal delivers superior optical performance for serious amateur and professional astronomers.
