If you look at an actual completed scope (see:
http://bhs.broo.k12.wv.us/homepage/alumni/dstevick/stevpaul.htm )
you can tell that the diagonal is located just below the dec axis from the
position of the focuser on the right (end).  Since you gain greater freedom
of position by placing the focuser on the "side" and that freedom is in the
direction of the top, it looks like the focuser could easily be placed in
the dec axis.  Only a minor lateral counterweitht (in the direction
perpendicular to both the dec axis and the primary optical axis) may be
necessary.

Can we figure out exactly how close this is to the CG (given some weight
assumption, say)?  I was curious if this would come out at the declination
bearing point of a fork, for instance.
