I just finished my first try to shoot the milky way over the Saxon Switzerland national park in Germany.
It's manual stacked with 8 exposures in Photoshop.
I had to stay between 3am and 4am on that place to have a view on the milky way.
At the end, the hardest thing is to manually focus correctly since you can barely see any stars through the camera.
Took me one and a half hour of post production in Lightroom and Photoshop.
Sigma 10-20mm f/3.5
10mm / f3.5
42 seconds per shot
