ATM Binos

["Frank Ward" <thewards@mindspring.com>]

I've just reviewed James' binoviewer and
was quite impressed with his work.  But it
leads to a basic question....what is the
difference when viewing between a bino
with two mirrors and a bino using a larger
mirror and a bino viewer.  The bino viewers
are quite expensive, but not as expensive
as constructing a two mirror scope.

I have adapted a microscope bino viewer
to my 5" f/5 and find the view really an improvement
over the monocular at the lower powers an f/5
demands. I'm trying to visualize the difference 
made by using two mirrors. 

Any help? Who's compared both?
