When I place my hand on top of the mount I can feel a small amount of slop in the RA axis, not much but I can detect no slop in the Dec axis. This mount is less than one year old but gets used a fair bit and some long sessions imaging. I did not notice slop until about three weeks ago. I have searched online and found Astrobaby's advice and instruction on adjusting the set screw - but before I do anything I need to ask - how much slop is enough to justify an adjustment and does it really matter when weight is on the mount.?
