Now that you’ve learned how to photograph the Milky Way, you may have noticed some nasty coloration around your stars. Resulting from close-but-not-quite-in-focus stars or shooting with a wide open aperture on a lens that isn’t perfect — star halos, chromatic aberration, or blooming can ruin an otherwise beautiful night-sky image. While looking through some of the photos from a recent trip to the beautiful dark skies of Namibia, I realized that shooting for 9-nights straight caused me to take a few shortcuts that bit me in the end. Some of my photos had ugly purple and blue rings around the stars! Luckily, fixing this problem with Lightroom or Photoshop is easy, and I’ll tell you about it here.
