A recent camp stay at Burlingame surprisingly put me very near to being in line with the north pole. I had basic photo gear with me but these days am usually primed for some timelapses, so quite literally all the stars aligned.
This started at around 9:00 PM, just barely within blue hour, and ran for about four hours. I was forced to setup with a road and bathrooms in front of me, which were busy enough within the first hour or two that their lights are clearly a part of this sequence. Later toward the early morning the extra lighting slowed down and even saw a bit of the Milky Way in the upper right corner.
I used about 350 images total for the time lapse and final composted image of star trails.
Enjoy!
