Hi Barry
When I am using the scope visually and I touch the scope it does vibrate for
about 5 to 10 seconds before it settles down steady again.
So what I do when taking photos is get it guiding using PHD (maybe I should try a different guide program) I get everything setup and then step outside my Observatory and trigger the camera via a cordless remote which lifts the mirror up and delays exposure for further 2 seconds to stop any additional vibration this is a function of the Nikon D300.
My balance is bad I know when I have scope horizontal and release clutch it sits still , but If I raise OTA straight up to meridian or really any higher than say 60 degrees its swings over itself. I am not sure if I should be adjusting weight everytime I move to new object I am photographing or just get scope reasonably balanced overall?
Below are some more photos of setup maybe someone has a better idea by seeing it.

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.
