Good point, I stand corrected on this issue. However, the force
applied
to the clutches is different...in the case of the Dec axis, the
weight
of the load, plus the tension of the clutch combine to make the
stiction load greater then the RA axis, which sees only the clutch
tension. The difference in the breakaway stiction force necessary
between the two axis is very noticeable. Thanks for correcting my
analysis. I am beginning to enjoy this group.

Bill, you're absolutely right - the DEC setting is a balance between easy
to move, and having to hold the scope when you take out that heavy
eyepiece! It's not so bad on the MCT, but the large refractor is a
challenge. I guess the solution is to install Scott's GoTo, and do
electric slewing! :-)
