Hi Bob,

Can you tell us how rigid it is? Does it hold its shape well enough to still 
focus properly when mounted by the edges and perhaps tilted at an angle?

Reflections of what, exactly? From what? Could you please explain further? I 
have a system ready to go (though using a smaller lens right now), but I'm 
the only one playing with this stuff here. So I'm curious when anybody says 
"reflections".
