Thanks very much for your interest and kind words, guys.
I'm too busy at the moment to reply individually , but I'm sure many of your questions would be answered on Bruce's webpage on his own prototype and pretty much identical instrument using Swayze mirrors.

Last night we tested Paul Shopis's 12" binocular with one complete and and one uncoated 12" mirror to test the system. They were very easy to collimate and use. A list of minor adjustments and fixes to be done so still a little way to completion .
