Slippery azimuth movement
|
I have since 2004 and Obsession 18" with Servocat and AN which is a fantastic scope.
However I have a little issue right now: the azimuth movement (in goto mode) is on some places "slippery".
What could be the reason? Could it be the ground board is worn out on those places (I don't see anything "wrong" there) ,
or could it be the tension of the spring which somewhat getting loose over time? But then why only on some places?
Did anyone experience this issue too?
