I did try sharp cap align once didn't have much luck with it, dont remember the issue, maybe my inability to point north with my mount. NINA's new plugin is real easy and gets you real close, review and tweak a couple settings the first time, then just hit run, it slews to your predetermined area of the sky (for me it was SW) takes 3 images x degrees apart, then plate solves them, gives you a visual indication of what direction to move and how much. very quick and very easy to use, no need to see polaris.
I live in NE too. I dont think my 36"x36"x36" block o concrete set 3" below grade to the top, has moved yet, but it's only been through 2 winters I think.
