Hey,
Have a 8" dobsonian collapsible, non goto, skywatcher.
It is smooth turning left and right.
But when it try to adjust up and down after tightening it, it is jerky. Jerks in the direction then eases back a bit. This is with the knobs tightened on the sides of the scope
Any trick to make it smooth up/down?
Loosen/tighten/oil something?
