De-Noising Choices for Night Sky Photographers

If you've taken high ISO images at night, you know how discouraging noise in your images can be. Until a few years ago, we relied on 'stacking' our images in Sequator to reduce, but not eliminate, noise. The buzz-term today is AI, which is now providing solutions for this problem. Here, I look at Lightroom Denoise AI, DxO PureRAW 3 and Topaz DeNoise, along with good old Sequator. And, surprisingly, combinations of Sequator and these AI solutions, where removal of aircraft or satellite trails is necessary.
