As the vegetation shows, most of the 'noise' is coming from space.
There is zero artificial light in this sky.

Good composition and silhouetted objects, I like it. The noise is distractingly strong, and I'm surprised so strong for 13s ISO 2000 exposures, especially with 6 shots to average out the noise. I wonder what processing you performed, if there's some suggestions that could be made to improve the noise.

Great photo Del.

Beautiful composition.
