If you think Polar is out work on it until it is not.. everything turns on having it better than perfect.
I must be honest and tell you that your focus is out...you have dounuts and that tells you that your focus needs improvement.
You need a focuser mask I expect...this sort of thing

Work on those two aspects and know this everyone starts with poor polar alignment and dounuts.
Blow your images up and examine them critically and accept nothing less than perfection and then some.
Thanks for posting and please keep sharing your progress and one day you will be as good as I would like to be.
