I just received my "new" intes mk 67, which I bought used for a very good price, but the focusser isn't working properly. When I turn the focusser, the inner tube moves, but with almost no force. So I guess I need to adjust the tension of the teflon bearing on the inner tube. Can anyone help on on which screws I need to adjust?
