This is not "A New Aspect" - It's a very old one that is only "new" to those not experienced with either telescopes or long telephotos.  Atmospheric haze, polarization, turbulence, and temperature/density gradients in the atmosphere play an important role in long distance tele work.

The OP's explanation is highly simplified as well - that's OK, but it's not the whole story.
