I don't think it's a problem. Many viewers may see this as a positive attribute. My semi-educated guess is that it's caused by diffraction due to water vapor. The brightness of the foreground on the left may be more of an issue -- I wish that could be toned down a bit. I think this is a very good photograph of the Great Plains: bright and smooth clouds, very distant trees that provide just a hint of relief on the horizon, a road that goes on forever, and the remnants of crops waiting for a new cycle -- it's a wonderful combination of elements.
