Understanding SNR Part 1 - What are signal and noise?

Описание к видео Understanding SNR Part 1 - What are signal and noise?

The first part of a multi-part series on SNR, Signal to Noise Ratio, in astrophotography.

In this, we discuss what signal and noise are, how we might assess them in our images, why we evaluate the quality of an image as a ratio between the two, and why the SNR matters to our ability to produce the image we want from the data we have.
