I sometimes pull all-nighters in the desert shooting Milky Way landscape images, and here is one from a session last month.
Fuji X-T2
Sky = 15 images track/stack with Rokinon 21mm
Ground = single image with Fuji 10-24.
All post done in Photoshop.
Quintessential Joshua Tree at night.
Nice shot. Light painting is hard. Next time I am going to set up a light panel on very low setting to the side I long way away if possible. Although it would be hard to set up with all the boulders in the way at Joshua tree. Love your composition.
