So I picked some western stars that were much further north and just peaking out from behind the roof of my house. I first went to Mizar -- I figured out that in the PWI app, you don't have to use just the couple of recommended stars in the alignment list, but you could click on any star on the map and use that as the alignment star.
That worked fine, but by this point clouds were rolling in, and it was hard to find stars. The clouds didn't show any sign of letting up, so I gave up on trying to image that night, and instead just put the caps and cover on and just took dark frames instead. Darn!
