Kent,

I'll be using them to mount my Pentax 67 and associated lenses.  The
lenses will be the "guidescope" per se.  This particular setup was
suggested by Michael Stecker in August 2002.

>For a guidescope, you don't want any movement AT ALL.

I suppose my title was a little misleading due to the fact the rings
will be holding my Pentax 67 lenses.  I was concerned the tips would
ruin the focus ring.  I'll be doing some experimenting over the next
several weeks to see if I have any flexure problems.  My main
concern now is determining how much to tighten the screws.  There's
probably a fine line between too little (i.e., flexure) and too much
(i.e., ruining the lens).  I'll probably end up grinding the tips
down to lessen the potential of flexure.  Nothing's worse then
spending all night taking astrophotos and getting them back with a
frame full of star drift.
