Can you tell us more about the mechanical details of this
device? Is this simply a 10" F17 objective with flat mirrors
to fold the path into a more compact layout? What sort of lens
is used - a conventional achromatic doublet, or is this one of
those designs (like a Schupmann) that uses auxiliary lenses to
color-correct the image from a large simple lens?
