What is binning? Why do you need 2x2 or 3x3 binning in astrophotography?

Binning is a term you've probably heard in connection with astrophotography. It's a very basic technique that combines, for example, 2x2 or 3x3 pixels into a single pixel. As always, in this video I'll explain very clearly where and why this binning technique can be beneficial. You'll learn an important way of thinking about camera chips that should help you fundamentally understand the technology of astrophotography. After the theory, I'll show you where binning is used today. And finally, you'll learn where you've used binning before without even realizing it.
