 When the telescope ( dob mount ) upper end is moved or nudged slightly in
altitude it wobles up and down starting in approx 1/2" arc for about 
3-4 seconds before stabilizing. The wobble and stabilizing time is less for
the horizontal back and forth movement . Is this typical and if not then
what might cause this?
