David Malin, an Australian astrophotographer, describes this quite well. While dslr cameras vary, the settings dont. On a dslr, 30 seconds at iso 3200 and your lenses widest aperture will suffice. But you want to go for the widest aperture lens possible. Mine is f/3.5.. Not quite wide enough, but it does the job. Ideally you want to be below f/3. The lower the f/ number, the more light gets in! You have to have a dslr to do this. Generally any high end or prosumer camera with manual mode will be able to capture something of the night sky. Just select the lowest f/ number at the longest exposure and the highest ISO your camera is capable of. I started with a Canon powershot A520. 15 second exposure, f/3.2 @iso 800.. the images werent spectacular. But it gave me a taste of what astrophotography was! https://youtube/watch?v=_kC1nKlIPU0
