Hi, I have added setting circles to the base of my 12inch SW Dob. I simply went to a printing shop, and asked them to print circles to the exact size for my base. They printed them on A2 paper for $0.40 each.

For the Altitude, I use a digtal protractor that is accurate to 1/10th of a degree. This, coupled with a laser level for the base marker, it is not hard to set up, and use with good success. I then read the AZ/Alt from a laptop program such as Stellarium for a particular target, and set up scope accordingly. Usually it is within the low magnification eyepieces view.
