    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.

      @[email protected] heavier, longer lenses also bring tripod quality into play. I have seen an $8k camera on a $45 tripod, next to a person quite frustrated with the image quality it gave them, blaming the camera.

      @[email protected] My astronomer friends might disagree that atmospheric effects are greater the further the astronomical subject.

      But aside from my poor (very poor) joke, has anyone doing terrestrial photography adopted the technique used by astronomers of using a laser beam to do real time measure of atmospheric conditions and use that either in real-time lens/mirror adaption or post processing?
