Greg, I may have this wrong but my impression is that on the Frieberger Yacht the physical horizon glass is half the 'normal' width but edge-to-edge silvered -- so in effect only the silvered 'half' of a traditional horizon mirror is physically there and that the clear view of the horizon is direct without intervening clear glass.

So, I was wondering if this would pose any challenges -- certainly to the extent that one gets some reflection on the non-silvered side of a traditional mirror, that would no longer be present (again if I have the Freiberger Yacht arrangement correct). I'm no optics expert, but the clear glass portion of a traditional horizon mirror must have some refractive index and this would no longer be present -- not sure if is this is negligible, a problem or a plus.
