I decided to make the 1024 images challenge myself to show how the stacking work and how it affects the signal to noise ratio (SNR). The result was the one I expected. Therefore you may watch this video and decide for yourself how many images you need to stack to get the image acceptable to you.
The equipment used to image the #Pleiades:
