While the focusing knob on my scope is easy to rotate, trying to do fine focusing isn't.
The problem is that the knob is just to small in diameter.
A larger diameter knob would make fine adjustments easier.
So one of the things I did was cut off 1 inch piece of foam from a foam pipe insulation whose center hole was slightly smaller than the focusing knob on the scope.
Then I slipped it over the focusing knob on the telescope.
What that did was increase the diameter of the focusing knob thus making it more like a 4:1 ratio (?). It has made fine focusing a bit easier for me.
UPDATE: If you fingers are slipping on the foam you may want to find wide rubber bands that will fit snuggly around the foam. It will make fine focusing a bit easier and more controllable.
A cheap temporary solution... here's some pics I just took of it:
