And this is why this process also goes under the name of background extraction. There is nothing wrong with it, as all the details and information are there, but hidden in the dark background. With deep sky astrophotography, this stacked image can be surprisingly dark, with only a few bright stars visible. With image stacking, you have combined all your light frames (the actual images of the sky) into a single image with an enhanced signal-to-noise ratio. What Histogram Stretching Is And Why You Need It Of the steps mentioned above, it is worth to spend a few words on the Histogram Stretching, as it is of utmost importance in deep-sky astrophotography. In astrophotography, the post-processing includes steps that are crucial to the quality of the final image. What Does Post-Processing Mean In Astrophotography?
