Baader Planetarium T-2 Maxbright Mirror Diagonal - 2"

The Baader Planetarium T-2 Maxbright Mirror Diagonal uses the proprietary Maxbright all-dielectric mirror coatings. This process results in an amazingly high 99% photo-visual reflectivity. The unique Baader Planetarium 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 35 mm (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 Planetarium 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.T-2 System Design: Like its correct-image sibling (the Precision Amici Diagonal), the design of the T-2 Maxbright Mirror Diagonal enables it to be configured to exactly suit your needs. The input and output T-2 threads integrate with the full range of Baader Planetarium Astro T-2 System components. It can be configured to install in 2" or 1.25" focusers, for use with all 1.25" eyepieces and even many 2" eyepieces. It is also the perfect diagonal for use with the Baader/Zeiss Giant Binoviewer (replaces the normal prism diagonal).Like all the Baader Planetarium products, the mechanical quality and finish are superb. The all-machined aluminum housing supports the mirror at the correct location and at a precise 45-degree angle to maintain the collimation and performance of your optical system. Even the tiniest exposed lips are sharp V-threaded for stray light control.
