That's why I said noise reduction. Blow out the bright stars to uniformity and squash the dim stars out of existence. Just heavy handed post processing is all, not fakery. Nobody would fake slightly trailed stars 😂 this sub sometimes

Zoom in, they're there. I do night photography so I know what to look for. I'd guess 2-5 second exposure.

I think the star issue is due to using too much noise reduction which deletes the dim stars. They're clearly not fake since they have realistic long exposure trails.
