Question regarding reflective coatings.
Here's hoping we'll soon see a Maxbright 1.25!
On another note, might Baader's new method eventually lead to successful dielectric coatings on Newtonian diagonals and eventually even primary mirrors? Unfortunately because the dollar has declined 25%, these smaller diagonals are quite expensive. You can always use a 2" diagonal with 1.25" and even .965" eyepieces. The diagonal will last forever, the eyepieces you will throw out much sooner. I'm not sure if he would make Newt diagonals. The process is more expensive than is worth for a typical Newt. The cleanability is not that important for a Newtonian where the light from each star or planet is spread out over a large portion of the surface. In a star diagonal where the eyepiece is closer to the diagonal surface, even small amounts of dust, dirt and crud have a very negative effect on planetary contrast - thus the desireability of the cleanable multi-layer dielectric coating.
