You can tell it was shot under excellent atmospheric conditions. The processing is also superb, with a bit of noise left in, so the noise reduction doesn't wash out the fine details in the background.

BXT was also applied here, so it's hard to judge the atmosphere now.) Where BXT wasn't used, I note that. If small stars show slightly wavy rays, it means BXT was applied.
