Hi Denis,

 

The tuning parameters depend on the telescope/camera combination, so it is difficult to comment on your numbers without knowing what the system is.

 

Vibration during slewing is usually a sign that the fast tuning parameters need to be backed off a little. It can also be a sign that the tripod is not solid enough or well enough damped.

Hi Denis,

I see in your picture, you have a 'rat-cage' on your pier. That kind of construction was the cause of unexpected vibrations in my mount...

I solved it by filling the threads up with nuts and keeping the topplate as close to the pier as possible.
