I have an Orange C8, beautiful scope, but the aluminum tripod was terrible. Very wobbly mess. I replaced the tripod with a Celestron Heavy Duty Field Tripod. It has 2" dia steel legs, extremely heavy duty castings. Very nice and solid tripod. So after replacing the tripod, I found the overall amplitude of vibration was greatly decreased, however the RINGING has nearly doubled. After focusing I must wait 9 seconds... and a sharp rap on the fork resonates for an excruciating 17 seconds! I can feel no vibration in the mount while it's ringing, only at the fork.
The only thing which stops the ringing is to grab both forks, or push up firmly on the fork housing... does not seem to be the wedge or tripod which is ringing.
Any ideas for a fix?
