Nettet29. feb. 2024 · With a given CCD camera, field of view is dependent only on focal length. This means a telescope which gives a greater image scale also gives a smaller field of view. Often this is not a problem since a large image scale is typically used to image smaller objects such as galaxies. The human eye has an average field of view of about 170-180 degrees. In photography, you can change the field of view by changing our lens. A wide-angle lens will allow you to capture more of a scene, while using a telephoto lens or moving the camera will decrease the field of view.
