From an all nighter within Joshua Tree NP. The sky was taken about 3 hours before I photographed the ground. I used my iOptron Sky Tracker Pro to get 3 tracked images, stack them for a little more noise reduction, and cleanup a couple airplane trails too.
Rokinon 12mm F/2
Sky = 3 tracked shots, (ISO 1600, 4 mins, F/2.8)
Ground = Single at sunrise blue hour, (ISO 400, 1/10th, F/5.6)
