It worked well for the photo above because the foreground and sky had a very distinct separation. However, astro trackers aren’t always ideal. I’ll start with the harder-to-implement method because it’s easier to explain. If you need to capture everything in one image for whatever reason, take a look at our tutorials on Milky Way photography, getting enough depth of field at night, and the optimal settings for star photography.) Stacking Method One: Use an Astro Tracker (All this assumes that you don’t have a problem with blending photos. Stacking photos essentially eliminates that problem.īut what do I mean by stacking photos? There are two routes, one of which is simpler and more flexible than the other.

Otherwise, you could shoot every Milky Way image at f/5.6 and 10 seconds (maximizing star sharpness) while simply using an insane ISO like 51,200 to get your image to be bright enough. What can you do about it? One answer is often overlooked, but surprisingly helpful and easy to put into practice: stacking images.įundamentally, the big problem with shooting the stars is that you lose a lot of image quality at ultra-high ISO values.

If you’ve ever tried to do astrophotography, you’ve probably run into all sorts of issues: blurred stars, high ISO noise, and shallow depth of field. The night sky is one of the most alluring subjects for landscape photographers.
