The result is a single image with improved signal to noise ratio, i.e., with better details and lower (random) digital noise and better details. In the simplest form of image stacking, the pixels values for all images in the stack are averaged to produce a single image. Each digital image is formed by a set of pixels, all having a certain value: dark pixels will have a lower value than the bright ones.A stack can be visualized as a pile of images all stacked one on top of the other.The concept behind image stacking is simple, but to appreciate how it works, there are a couple of things we have to consider:

Note: Don’t miss the detailed video at the end of this article, It was created to help show you how to quickly start using some of the stacking software mentioned in this article.Ĭlick here to skip to our Image Stacking Demo Video.Ĩ) Conclusion What Does Stacking Photos Mean? This article will help you find which is best for you. There are many astro stacking programs to choose from. In this article, we will discuss some of the most popular software available for astrophotography image stacking. Image stacking is the technique used to improve the signal to noise ratio, and it is the only noise reduction method that will boost the image details rather than smear them out. Reduce noise and deal with light gradients and vignetting.In astrophotography you cannot avoid post processing your images, so stacking and editing your images serves three main purposes: Astrophotography is closer to science than art, and there is no such thing as “getting it right in camera.” This means you cannot simply point the camera at the sky and snap away.
