Baader T2 Maxbright diagonal mirror - dual T2-threads

One of the best T2 and 1.25" star diagonal mirrors we know

The Baader Maxbright diagonal mirror is more than only a high-quality alternative to other systems. It has the following advantages:

99% reflectivity with dielectrical coatings according to ZEISS company standard

very robust metal body with T2 threads on both sides

excellent optical quality

offers 35 mm clear aperture - significantly more than with standard 1.25" systems

even usable with 2" eyepieces

The shortest 2" diagonal mirror we know

The T2 Maxbright diagnoal allows 2" adaptations if adapters are used.

This makes sense with telescopes who have a short back focus where normal 2" diagonals can´t be used. One example is the Pentax 75 SDHF.

You can use 2" eyepieces up to ca. 40 mm field stop diameter. The picture remains steady. You only have small vignetting on the outer rim of the image.

In oposite, 1.25" diagonals have maximal approx. 27 mm of free aperture. So you gain 30% with the Baader Maxbright T2 system.
