Happy Thanksgiving to those who celebrate.
I received my electronics and motors back from the repair shop and the Dec reversal has been fixed. After putting everything back, I am ready to lift the scope to my pier and noticed the R.A. Setting Circle cannot manually be turned far enough in east or west to bring the "0" to align with the Hour Angle Pointer. There are hard stops in either direction when moving the setting circle. I am polar aligned and before powering up I always move the R.A. Setting Circle to the "0" position. What did I manually do during reassembly that is preventing the R.A. Setting Circle to move far enough to the "0" position? Attached photo shows Setting Circle at the hard stop when moving counterclockwise.
