Hi Richard,

We might be talking about different things, but I
think Nils description is accurate.  While octagons
are possible, that is not the most common geometry in
the ubiquitous Obsession-class scopes. In plan view,
the most common arrangement of an 8-pole truss is a
square, with the mirror-box pole clamps in the
corners, and the UTA clamps at the midpoints of the
sides of the square (or at 3-6-9-12 o'clock on the
ring.  This avoids the compound angles in an octagonal
arrangement.

Best,
Ross
