I've been getting by for several weeks with my CEM70 mount. I have been through several polar alignments and now have the mount permanently mounted and have a question regarding the zero position.
Say that one has re-set the zero position, done a precise PA and then later releases either (or both) the RA and DEC "clutches" (say for balancing adjustment) and does not re-engage them in the exact same location. Will the home position change ? If so, this will affect the PA, correct?
