Looking at those shots. If they are all of the same time. The first thing I see is the movement is not constant. I suspect you have more than one problem. Balance could be a problem. Is it exact or have you got a bias to get a positive drive. Vibration appears to be the main trouble. This could be causing flexing as well.
That scope is pretty big to be stable on a simple wedge. When you use the scope visually does touching the OTA move the view. Fork mounted SCT's have an awful lot of overhang on the main base.
