The R.A. setting circle is now aligned and ready to use. The R.A. setting circle is clutched to the R.A. gear
rotation. As long as the drive is operating, the circle does not need to be reset once indexed to the correct
coordinate (i.e., once aligned). If the drive is ever turned off, then the R.A. setting circle must be reset
once reactivated.
