A simple focuser mask can be made using a cardboard disk with two holes of the same size on the diameter line...say 2 inches from the center and the holes say one inch in diameter...we used this method in days gone by that few know about it these days...cheap and way better than nothing but you will need to focus on a bright star...anyways cover your scopes big end and when focused you will only see one hole in fov..
You need a polar alignment method past the star slignment ...I use a system called Polemaster ...you have a camera in the Polar scope hole and a program that gets you spot on ... There are other ways within capture software but I have not used that and cant remember which software.. someone will I expect.
