Hi Jerry, 
Here is a modified .len file that includes a diagonal flat before the focus
to give it a more accessible focus location.  I didn't include it in the
previous .len file because it did not contribute to the analysis of the
image.  Unlike David Stevick's plan 
(see http://bhs.broo.k12.wv.us/homepage/alumni/dstevick/sptbrief.htm )
in which the diagonal directs the final light path across the light path
between the secondary and tertiary mirrors, this plan directs final light
path out the side, giving greater leeway since the final distance is
shorter.  To see how this works out, use the 3D lens drawing or the 2D "top"
view (from the menu, select Lens/Lens Drawing/System... Then under View
type, pick X view).  Note that the diagonal does not change the analysis
reports.

So it is not "fat chance".
Clear skies,
Don
