I have found an optical coating service that will coat optics, in small batches for a ""reasonable"" fee. I am considering having the objectives and prisms coated with broad band coating. I was wondering what the group thought of this idea? This would improve the light transmission at 4 surfaces. I realize the eyepieces would still loose a fair bit of light.
Second question is that the service was concerned about coating cemented objectives of 80mm diameter, and suggested that the two elements be coated separately and glued together due to stress of differential thermal expansion, between flint and crown. Anyone know if this is a valid concern?
Thanks for input and comments.
If this succeeds I will due my U-boat 8 x 60's RA's next.....

There were 6 companies in Germany/Austria/Poland that made these binoculars. They were designed by Emil Busch, A.G., but such companies as Leitz, Schneider, and Fuess also made them. I happen to collect them by manufacturer as designated by the 3 letter code on the R. prism housing. There were also some 10x80 Flakfernrohr binos manufactured by Zeiss that were 90 degree viewing angle glasses. Perhaps rarer than the binoculars themselves were the alt-az mounts.
