If you have ASCOM and computer, I'd recommend using that over hand controller. Free software solution/suggestions:
1. Drift align for more accuracy over your "rough" polar alignment. OpenPHD/PHD2 has a drift align tool that's simple and effective. If you use other guide software, you could use that assuming you can turn off DEC guiding and see a trend line of errors.
2. Then blind plate solve for star alignment. AstroTortilla and/or a local astronomy.net solution is free.
3. Done.
Might be able to add more detail or tweak recommendations if you let us know what guiding software and image capture software you have already.
