There are a number of solutions to this question. A non goto dob or one without digital setting circles (eg. Argo Navis) is usually moved by star hopping. if attempting to move a number of degrees, you can use your finder. A 9x50 Finder has a field of roughly 5 degrees, so if you know what direction to move, place the moon at the edge of the field, then hop three more field until you are close. Of course to make this work you may have to learn celestial directions, moving N,S,E and W in the sky can be counterintuitive.
It is possible to use analog setting circles on a dob. The inclinometer mentioned earlier and azimuth circle on your base enable you to work out the alt as settings that apply to an object at any particular time and then point the scope. This will only work accurately if your base is obsilutely level.
