Baader Planetarium has just expanded their innovation in star diagonals. With their ground-breaking introduction several years ago of their all-dielectric 2" Maxbright star diagonal, Baader brought mirror star diagonals into the 21st century. The mid-size, flexibility, and cost of the T-2 Maxbright Mirror Diagonal make this the ultimate diagonal for high power planetary viewing, or in systems where back-focus or space is limited and a full aperture 2" diagonal will not work or is not flexible enough.
The new T-2 Maxbright Mirror Diagonal uses the proprietary Baader Maxbright all-dielectric mirror coatings. This process results in an amazingly high 99% photo-visual reflectivity. The unique Baader coating system has also been specifically optimized to minimize scatter, and does NOT degrade mirror flatness. The zero expansion mirror substrate retains its true 1/10 wave (p-v) flatness over the entire oversized 35mm (1.38") mirror surface! This allows the mirror to be used well in front of the image plane with no image degradation or astigmatism from a warped mirror surface. In addition, the extreme coating hardness makes the Baader Maxbright highly durable (the coatings are harder than the glass itself!). The Maxbright mirror coatings will last lifetimes without losing reflectivity, and may be cleaned with normal care, without fear of scratches.
