The camera battery died at about 4:00 am and I did not wake up to replace it till 4:30am so you will see a little gap in the time lapse video at the end. You will also see in the time lapse that the moon set around 3:00am. I put together star trails of all images as well as separate stacks of before and after the moon set.
First, here is a stacked photo of all 565 images including the eventual sunrise which really washes out the image. Next time I will only include a few images to the beginning of twilight. It appears that either the north star rotates slightly or my tripod was not very stable during the night.
And finally, here is a stack using only images taken after the moon set at 3am.
I put the following time lapse video together using all images. You may notice a skip around the 30 second mark when the camera battery died. I really liked the beginning of twilight so I kept the final 7 seconds in the video. Next time I will just start shooting later in the evening so that the camera battery lasts all the way through twilight. I was able to shoot continuously for almost 4.5 hours (480 images) by turning off the display and image review.
