A magnetic protractor is a cheap and easy solution to setting the tilt angle of the mount to the local latitude.

How does that work ?

I used one for many years with a German equatorial mount. The protractor has a magnetic base that will affix it to a flat metal surface and will indicate the tilt angle of the mount. The celestial pole's elevation above your local horizon is equal to your local latitude. Set the tilt of the mount to your local latitude.

The final step is to set the mount's azimuth equal to true North. This can be done with a compass as long as you offset for the deviation of magnetic North from true North for your locale.
