Ah. So where it says "Mirror face to focuser Hole = 27.435", that
would be 27.435" to the center of the focuser hole?

Also, newt reports that my diagonal (is too small to admit 100%
ray. It says the 100% illumination diameter is -0.063. Is this a
problem? My diagonal is 1.2" for a 6" f5.9.

Thanks.
