While Image stacking creates a cleaner image, it often softens the image: digital sharpening techniques are then used to recover sharp looking details.ДЇinally, bear in mind that the progression of image quality is not linear. The more images you stack, the cleaner the resulting images are, as shown in the comparison below. As you can see, the original images showed a greater deal of noise (grain) than the stacked one.

The image below shows a real-life example from stacking 30 images from my Sony RX10 bridge camera taken at ISO 6400. ISO noise and Luminance noise and Chrominance noise are examples of digital noises that are random. If the considered digital noise affects the pixel values randomly across the stack, then the result of averaging the stack is that the random component of the noise to the pixel value is significantly reduced. The scheme below illustrates the concept. 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: DonвЂ™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.Д¬lick here to skip to our Image Stacking Demo Video. 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. In my experience, Registax and similar programs cannot cope with uncropped DSLR images - it would require the allocation of far too much memory. A very comfortable innovation:) Here is the first step of my usual processing routine.

With Registax 6, the gaussian blur is completely integrated to the processing software and you drive it like the wavelets, with sliders. See images below for after stacking and then after Registax (using Andrews recently posted Jupiter scheme that he used on.

I imaged Jupiter for the first time in 5 years the other night. Reduce noise and deal with light gradients and vignetting.ДЇirst Jupiter attempt in 5 years - Registax schemes suggestions? - posted in Major & Minor Planetary Imaging: I originally posted this in the wrong section of the forum, so it was suggested that I post in here.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 вЂњgetting it right in camera.вЂќ This means you cannot simply point the camera at the sky and snap away.
