    One of the challenges of very long lenses is that they tempt you to compose images of subjects that are very far away. But the farther away something is, the more the atmosphere can distort the image. The effects of heat distortion, pollution, humidity, and weather are amplified across longer distances, no matter how sharp the lens is or how high resolution the sensor.

      @mattblaze@federate.social one of the coolest ways to observe this phenomenon is to look through a telescope, basically the same thing as a telephoto lens. The big observatories have some awesome ways to correct for atmospheric distortion, including lasers!
