Hi Wavy.
Film certainly predates my attempts.
That how I would polar align.
Place scope in home position, take an exposure, adjust the mount, take another, adjust and so on until the stars were rotating with their center in the shot.
A compass only shows magnetic North and that's 12 degrees ( I think) away from true North, so if your scope is lined up using a compass its really a long way off.
Anyways so easy with a DSLR just on a tripod and its normal lens to work it out...
Now get ready for folk asking...what is film?
