Re: [ATM] Hyperbola? Warm pitch strikes again...

That is one approach that can work.  The thing here is that the
Hindle sphere needs to be abouty 1/2 the ROC of the primary for
the scope so you will be doing a lot of grinding on that one
piece of glass.  I'd probably just make the Hindle sphere and do
a seperate primary piece of glass as the Hindle sphere is always
useful for another secondary.
