Is it better to buy a digital camera or an ordinary camera from the quality of long-distance photography? Thank you. What are the advantages of both?

From the perspective of imaging principle, it is almost the same, except that the camera is better in picture processing, but this is related to the focal length. It is definitely better when the subject is within the effective focal length range of the camera. In this case, the digital telescope is more dominant. As for which one you want to buy, it is more important to see your intention. If it is mainly used for viewing or watching, you need to buy a telescope. If you want to collect information, you will naturally choose a camera.
